A Vaayu at ₹11,999 is wasted here, and I would rather say so than sell one. It is rated to roughly 2,000–3,000 sq ft; pointing that at a 120 sq ft room buys a machine that spends its life at the bottom of its range.
Reed count is your volume control, and the only one a reed bottle has. Six reeds is the calibration for a room; three is the calibration for a small one, and it makes the bottle last longer.
What this page will not claim: fragrance does not calm anyone, shorten a wait, improve comfort or aid recovery, and nothing here is medical, clinical or safety advice. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free and why the practice — not SOSA — sets its own policy.
Sukoon 500ml₹1,899 · lowest settingIn a large reception the seat furthest from the source is eight or ten metres away, and that distance does real work. In a 120 sq ft room the furthest chair is perhaps three and a half metres away, and no seat counts as a long way off. Two things follow. Placement can no longer rescue an over-set source, so the setting has to be right rather than the position clever. And a fragrance-free seat — the chair you offer somebody who would rather not sit in scented air — may not exist in a small waiting room at all. If your only seating is one small room, the honest options are a very low dose, a machine you can switch off, or nothing.

SOSA range, specifications and prices used in this guide (verified August 2026): Vaayu ₹11,999 — waterless cold-air nebulisation of undiluted fragrance oil; no water, no heat, no added humidity, no white mineral dust. Coverage up to 1000 m³, about 2,000–3,000 sq ft. 400ml refillable tank lasting roughly 90+ days at a mid setting. Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. SOSA does not currently sell a separate Vaayu cold-air refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, so a practice planning continuous or multi-site use should confirm current refill availability with SOSA before committing. The water-based Hotel Collection is made for ultrasonic machines and must not be used in a Vaayu. Other machines: Boond 300ml ₹899 (~150 sq ft, ultrasonic) · Sukoon 500ml ₹1,899 (270–320 sq ft, 16–18 hours on low, remote and steady/2H/4H timers, three 15ml fragrances included, ultrasonic) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine that covers less than a Sukoon, never a coverage upgrade) · Safar ₹3,999 (waterless cold diffusion, cordless, 20ml, about 6.9cm, three speeds, 1/2/3-hour auto-off — sold as a car and travel diffuser, personal-scale only; SOSA publishes no coverage figure for it) · Aangan ₹25,999 (HVAC nebulising, ~8,000–10,000 sq ft) · Meenar ₹38,500 (commercial HVAC, 12,000–18,000 sq ft). Water-based Hotel Collection for ultrasonic machines: 15ml ₹299 · 100ml ₹999 · 300ml ₹1,799 · pack of seven ₹1,799; scents are inspired by the atmosphere of well-known hotels — SOSA is an independent Indian brand and is not affiliated with, endorsed by or supplying any hotel group. Reed diffusers ₹749–₹1,349 (50ml 6–8 weeks, 130ml 14–18 weeks, six fibre reeds, no 100ml size; replacement reeds are not sold separately). Reed oil cannot be used in an ultrasonic machine and Hotel Collection oil cannot be used in reeds. SOSA sells no room spray or home spray — every SOSA spray is a car perfume. Nothing in this guide is medical, clinical or safety advice. A fragrance diffuser adds a scent to the air. It does not clean, purify, filter, sanitise or disinfect air, does not remove or neutralise disinfectant, damp or occupancy smells, and has no effect on comfort, anxiety, waiting time, recovery or any clinical outcome. Some people are sensitive to airborne fragrance, which is why this guide recommends that examination rooms, diagnostic areas, consultation cabins, procedure suites and post-operative areas remain fragrance-free, that a fragrance-free seating option always exist, and that a diffuser is never mounted into shared HVAC in a clinical building. Decisions about clinical policy, ventilation standards, infection control and patient suitability rest entirely with the practice and its clinicians. A persistent stale, damp or disinfectant smell is a ventilation, moisture or cleaning problem — SOSA sells no dehumidifier and no air purifier, and fragrance should never be used to cover one. Coverage, runtime and longevity figures are manufacturer specifications and typical ranges, not guarantees, and vary with room volume, ceiling height, air exchange, occupancy and season. SOSA publishes no commercial or bulk pricing, no corporate account, no annual maintenance contract, no installation service, no stated warranty term and no multi-location programme; warranty length, spare parts, servicing and app platform availability are unconfirmed, and larger or multi-site enquiries should go through the contact page before any commitment.

Most scenting advice solves the opposite problem to yours: it assumes a big room and a weak source, and spends its energy getting more fragrance into more air. In a waiting room under about 150 square feet none of that applies — there is no coverage problem, and every mistake available to you runs in one direction, which is too much. The work here is subtraction. Buy a small product, run it at a fraction of what it can do, and resist every instinct to add. Before any of it, the boundary this subject rests on: reception and waiting are hospitality space, while diagnostics, examination rooms, consultation cabins, the procedure suite and any post-operative area are clinical space, and nothing I sell goes into them.
Quick answers — read this first
Under ~150 sq ft you have a dosing problem, never a coverage problem. One reed diffuser at ₹749–₹1,349 with three reeds in the bottle instead of six, or a Sukoon at ₹1,899 on its lowest intensity with the 2H timer, is the whole specification.A Vaayu at ₹11,999 is wasted here, and I would rather say so than sell one.

The short answer
Short answer: one small source, half-loaded, away from the seating and away from the corridor to consultation. Under about 150 sq ft that is a Mountain Breeze reed diffuser at three reeds, or a Sukoon at its lowest setting if you want an off switch. Nothing larger, nothing second.
Why a small room over-scents so easily: a source emits at a rate set by the product, not by the room. Put the same output into a third of the volume and the concentration is roughly three times higher — and nobody sits more than two or three metres from it, so there is no distance available to thin it. A small room removes both of the mechanisms that make a normal dose moderate.

Straight answer
How do I scent a small clinic waiting room without overpowering it?
1. Buy the smallest thing that will do it, then run it below its smallest setting. Under about 150 sq ft the specification is one reed diffuser with three of its six reeds in the bottle, or a Sukoon at ₹1,899 on its lowest intensity with the 2H timer. Both are deliberately under-run, and that is the correct dose for the volume rather than caution for its own sake.
2. A Vaayu here is wasted, and I will not pretend otherwise. At ₹11,999 it is rated for up to 1000 m³ — roughly 2,000 to 3,000 sq ft. In a 120 sq ft reception you are paying for range you cannot use and then working to suppress the output you did buy. It is not unsuitable; it is the wrong size.
3. Reed count is the volume control. Six fibre reeds is the calibration I compose to, and it assumes a room. Three reeds in a small reception is the version that fits, and it stretches the bottle beyond the rated 6–8 weeks for a 50ml or 14–18 weeks for a 130ml at ₹1,349.
4. Place it at the far end from the chairs, not on the desk. As far from the seating as the room allows, at waist to chest height, on a tray, out of reach, and never in the mouth of the corridor to consultation. A source on the reception counter is the commonest siting error in a small clinic, because that is where staff sit all day.
5. Set the level for the fortieth minute and for the front desk. What registers faintly on walking in is a great deal more than faint after half an hour in the chair, and your receptionist is in that air all day. Your own nose adapts within minutes, which makes you the least reliable instrument in the practice.
6. Do not add a second source, ever, in a room this size. In 120 sq ft there is no other end to put it at — the two share the same air and you have doubled the dose. And keep the clinical pathway clear: examination rooms, refraction and diagnostics, consultation cabins, dilation bays, the procedure suite and post-operative areas get nothing. Ventilation, cleaning protocol and patient suitability are decisions for you and your clinicians, not for me.

TL;DR: under ~150 sq ft, one reed diffuser from ₹749 at three reeds, or a Sukoon ₹1,899 on its lowest setting with the 2H timer. Far end from the chairs, never on the desk, never at the corridor mouth, no second bottle. A Vaayu at ₹11,999 is wasted at this size.
The small-room specification, half-loaded
SOSA Mountain Breeze · Himalayan pine, sage & Indian cedar ₹849 / 50ml
Pine and sage over Indian cedar — dry, green and woody, with no sweetness and no floral weight, which is why it is the composition I put in a clinic arrival zone. In a small waiting room, start with three of the six fibre reeds and keep the rest in the box. Fibre rather than rattan, because rattan's pores clog in Indian humidity; alcohol-free, phthalate-free and low-VOC on a heat-stable coconut-derived carrier. 50ml runs 6–8 weeks at six reeds, 130ml ₹1,349 runs 14–18 weeks — the larger bottle buys duration, never reach. Stand it on a tray: the oil marks stone and wood.
Part one — why small rooms only fail in one direction
A large reception can go wrong in two directions: too much at one end, too little at the other. A small one can only go wrong in one direction, which turns a difficult judgement into a discipline. Three things explain why, and each argues for less.
1
FACTOR ONE · THE MATHS OF A SMALL VOLUME
The product's output is fixed; only your room's size varies
A reed bottle or a diffuser head releases fragrance at a rate set by the product — its formulation, its reed count, its intensity setting. That rate does not consult your floor plan. Put the same source into 120 sq ft rather than 320 and it is sharing roughly a third of the air, so the concentration is about three times what the product was calibrated for. The correction is arithmetic rather than taste: you do not want a gentler fragrance, you want less of the one you have.
The rule: a third of the room means about a third of the source. Halve the reeds before you consider changing the scent.
2
FACTOR TWO · THERE IS NOWHERE TO STAND BACK TO
Distance is a dilution mechanism, and a small room does not have any
Sukoon 500ml₹1,899 · lowest settingIn a large reception the seat furthest from the source is eight or ten metres away, and that distance does real work. In a 120 sq ft room the furthest chair is perhaps three and a half metres away, and no seat counts as a long way off. Two things follow. Placement can no longer rescue an over-set source, so the setting has to be right rather than the position clever. And a fragrance-free seat — the chair you offer somebody who would rather not sit in scented air — may not exist in a small waiting room at all. If your only seating is one small room, the honest options are a very low dose, a machine you can switch off, or nothing.
Test it in a minute: stand at the furthest seat from the source. Under four metres, and you are dosing the whole room rather than one end of it.
3
FACTOR THREE · WHAT YOU CAN UNDO, AND HOW FAST
A small room rewards a product you can turn down within the hour
Every format has a different reversal time, and in a small room that matters more than coverage. A machine has an off switch and an intensity dial: too strong at eleven is fixable by noon. A reed diffuser has neither, and its only correction is to pull reeds out — which works slowly, because the fragrance already in the room and in the soft furnishing does not leave when the reeds do. Expect a day or two, not an hour. That is the nature of a passive capillary product rather than a fault, and it is why I would start a small clinic at three reeds instead of starting at six and cutting back. The Sukoon earns its extra thousand rupees over the Boond for reasons unrelated to coverage: a remote, steady/2H/4H timers, sixteen to eighteen hours on low.
Part two — eight ways to scent 120 sq ft, judged
Take a real small waiting area: around 120 square feet, eight or nine chairs, one door to the street and one corridor to consultation. Here is what each option a practice that size might consider produces.
The small-room options · what each produces in 120 sq ft
Eight specifications, with the dial each leaves you holding
| The specification | What it produces in this room | The dial you are left with | Verdict |
|---|---|---|---|
| One reed diffuser, three reeds ★ | A low, even presence with no strong corner; the bottle lasts longer | One reed at a time, with a day or two to settle | The specification. Change nothing for a fortnight |
| One reed diffuser, all six reeds | The calibration for a room two to three times this size | Pull reeds — slow, because the room holds what is in it | Too much here. Not wrong in a bigger reception |
| Two reed diffusers at opposite ends | Double the output into one small volume; the ends are not far apart | Nothing useful — you have added, not distributed | No. The commonest small-room mistake |
| Boond ₹899, rated ~150 sq ft | Correctly sized on paper; six hours a fill; adds humidity | On or off, and a fill level | Workable and cheap, if the room is genuinely tiny |
| Sukoon ₹1,899, lowest intensity, 2H timer | Short windows rather than continuous; 16–18 hrs on low | Intensity, timer, remote — the most control at this price | The right answer if you want an off switch |
| Megh ₹3,499, because it is bigger | ~100 hours of runtime, about 215 sq ft — less than a Sukoon | Runtime. It is a tank, not a reach upgrade | No. Megh is never a coverage step up |
| Vaayu ₹11,999 on its lowest setting | Rated to 2,000–3,000 sq ft, suppressed to a tenth of its range | Excellent controls you did not need to buy | Wasted at this size, and I would rather lose the sale |
| Nothing at all | Clean, moving air; a room judged on how it looks and sounds | Ventilation, cleaning, and the seating you chose | A good answer, and the right one for several small practices |
| The honest caveat: these judgements describe how much fragrance ends up in a small volume of air, not how anybody experiences it. No claim is made about comfort, anxiety, perceived waiting time, recovery or any clinical outcome, and no product is described as safe or unsuitable for any patient group. Coverage figures are manufacturer specifications and vary with ceiling height, air exchange and occupancy. Whether fragrance belongs in your building is a judgement for you and your clinicians. | |||

The SOSA principle
A small room does not need a smaller share of your attention — it needs a smaller share of the product. Buy the sized item, run it at half of what it can do, and treat every impulse to add as a sign your own nose has adapted.
Which is why the most expensive machine in the range is the wrong answer for the smallest room.
Part three — when a small clinic should not do this at all
Small receptions produce more of the cases in which I would talk a practice out of buying, and the first is ventilation. A small room with modest air exchange is a room where whatever you add stays. If your front area already smells closed by mid-afternoon — and small, sealed, air-conditioned receptions often do — fragrance is going into air that is not leaving, and the result reads heavier rather than fresher. That is a ventilation question with a ventilation answer, and it costs nothing to test. A diffuser adds a scent alongside what is already in the air; it removes nothing.
The second case is the one from Part one: a waiting area that is a single small room with no alternative seating. A practice that scents its reception should be able to seat somebody where the fragrance does not reach, and in 120 square feet there may be no such seat. If a second room, a corridor bench or an office chair can be offered, staff knowing about it solves the problem. If not, either the dose has to be very low or the machine has to be one reception can switch off in a moment — which argues for the Sukoon over a reed bottle. The third case is a children's eye clinic or a large paediatric caseload, and there I would decline outright rather than argue about settings.
The fourth is a small practice planning ahead to a signature — one scent held constant, perhaps across a second branch. That is a commitment to buying the same consumable for years, and there is a live gap I would rather state than let you find. SOSA does not currently sell a separate cold-air refill oil for the Vaayu. The 400ml in the box lasts roughly ninety days or more at a mid setting and is the whole supply at the time of writing. The water-based Hotel Collection is made for ultrasonic machines and is not a Vaayu refill. Confirm availability through the contact page before committing a practice to continuous or multi-site use.
In a small waiting room no clever placement rescues an over-set source. The only control you have is how much you started with.
— Sonal Sahani, SOSA
Part four — what to specify, and what to take out first
Measure reception plus seating and ignore the consulting rooms. The last column is the part to read twice: what you take out first when the room is too much.
Sized down, deliberately
Six small arrival zones, and the first thing to subtract
| Your small arrival zone | Specify | Starting setting | First thing to subtract if it is too much |
|---|---|---|---|
| Under ~100 sq ft, four to six chairs ★ | Mountain Breeze 50ml ₹849, on a tray, far corner | Two reeds. Not three, and certainly not six | One reed, then two days before judging it again |
| ~100–150 sq ft, eight to ten chairs, quiet list | Mountain Breeze 130ml ₹1,349, for the 14–18 week life | Three reeds, away from seating and the corridor mouth | Move it further from the chairs, then drop to two reeds |
| ~100–150 sq ft, but you want an off switch | Sukoon ₹1,899 with a 15ml Hotel Collection scent | Lowest intensity, 2H timer, never steady | Halve the run window before touching the intensity |
| A tiny front room under ~80 sq ft, one bench | Boond ₹899, or a reed bottle at one reed | Short bursts; the room reaches its level in minutes | Switch it off through your busiest hour |
| Small reception that smells closed by afternoon | Nothing yet. Air exchange first, then re-test in a fortnight | ₹0 today | The fragrance — it is not what that room is asking for |
| Small reception, large paediatric caseload | Nothing. The one I decline outright | ₹0 | Not applicable — do not start |
Honest notes for buyers: nothing here is medical, clinical or safety advice, and no SOSA product is described as safe or unsuitable for any patient group — that judgement belongs to the practice and its clinicians. A diffuser adds a scent to the air; it does not clean, purify, filter, sanitise or disinfect air, and does not remove disinfectant, damp or occupancy smells. No claim is made about comfort, anxiety, perceived waiting time, recovery, reviews, footfall or revenue. Some people are sensitive to airborne fragrance, which is why the clinical pathway stays fragrance-free. Coverage figures are manufacturer specifications and vary with ceiling height, air exchange and occupancy. Megh at ₹3,499 covers about 215 sq ft — less than a Sukoon — so it is a runtime machine, never a coverage upgrade. Safar at ₹3,999 has no published coverage figure. Replacement reeds are not sold separately. SOSA sells no room spray; every SOSA spray is a car perfume, and no bulk pricing, corporate account, maintenance contract, installation service or warranty term is published — ask through the contact page first. Free shipping above ₹499.
The smallest machine in the range, and sometimes the right one
SOSA Boond · 300ml ultrasonic, ~150 sq ft ₹899
Rated at about 150 sq ft, roughly six hours from a fill, USB-powered, with a colour night light you will want switched off in a clinic. In a very small front room it is genuinely the sized product, and at ₹899 the cheapest way to own something with an off switch. What it lacks is the Sukoon's intensity control, remote and 2H/4H timers — in a clinic those earn the extra thousand rupees more often than the coverage does. Both are ultrasonic and add a little humidity, worth knowing before siting either near paper records or spectacle stock.

A note from Sonal
A practice manager wrote to me about a reception of about a hundred and ten square feet. She had bought two of our 130ml bottles — one at each end, six reeds in each — and the front of her clinic had become, in her words, a great deal more than she intended. Her question was which of our scents was gentler. The answer was that none of them would help, because she was running four times the source that room could take.
We took one bottle out and reduced the other to three reeds. A fortnight later she wrote to say the room had settled into something she stopped thinking about, which is the outcome I want in a clinic — and the remaining bottle outlasted the pair, so the correction cost her nothing.
I tell that story often because the instinct in a quiet-seeming room is always to add, and in a small room adding is almost always wrong. A nose that passes a reception forty times a day stops reporting a constant within minutes, so the person least able to judge the level owns the building. Ask the front desk instead. Made in Pune in small batches, and a part of every order funds a girl's classroom through Nanhi Kali.
Frequently asked questions
Is a Vaayu ever justified in a small clinic reception?
No. The Vaayu at ₹11,999 is rated for up to 1000 m³, roughly 2,000–3,000 sq ft, so under 150 sq ft you are buying range you cannot use. Its genuinely useful features — under 38 dB, key-lock, scheduled run windows — start to matter in a large open reception. If control is what you want at this size, the Sukoon at ₹1,899 gives you an off switch, a timer and an intensity setting for a ninth of the money.
How many reeds should I use in a small waiting room?
Three, and two if the room is under about 100 sq ft. Six fibre reeds is the calibration the composition is built around, and it assumes a room rather than a small front area. Reed count is the only volume control a reed diffuser has, and using fewer stretches the bottle beyond its rated 6–8 weeks for a 50ml. Add a reed only after a fortnight. Replacement reeds are not sold separately, so keep the ones you take out.
My small reception seems to smell of nothing after a week — should I add another bottle?
Almost certainly not. Your nose stops reporting a constant within minutes and adapts hardest in a building you enter every day, so a room that seems quiet to you is often not quiet. Ask your front-desk staff instead. In a room this small a second bottle is not distribution — it is double the dose in the same air.
Where exactly should the source go in a small waiting room?
As far from the chairs as the room allows, at waist to chest height, on a tray, out of patient reach — and set back from the corridor to consultation, because whatever sits in that corridor arrives in the cabins. Not on the reception counter, where staff sit all day. Never inside the return-air path of the air-conditioning, and never mounted into shared ducting in a clinical building.
Can I scent a small reception and leave the rest of the clinic neutral?
Yes, and it is the recommended arrangement throughout this cluster — reception and waiting at a low level, everything past the consultation door left alone. It takes door discipline, a source sited well back from the corridor, and no fragrance mounted into the central air-conditioning. Whether any of it suits your building is a clinical judgement for your clinicians, and SOSA does not advise into it.
Eye clinics · small arrival zones
Under 150 sq ft the job is subtraction — a small product, half-loaded, and nothing second
One reed diffuser from ₹749 at three reeds rather than six is the specification for most small clinic receptions; a Sukoon at ₹1,899 on its lowest intensity with the 2H timer if you want an off switch; a Boond at ₹899 in a very small front room. A Vaayu at ₹11,999 is rated to 2,000–3,000 sq ft and is wasted here. A diffuser adds a scent to the air; it does not clean or purify air, remove any existing smell, or have any clinical effect.

No hotel group is a SOSA customer, partner or reference.SOSA range, specifications and prices used in this guide (verified August 2026): Vaayu ₹11,999 — waterless cold-air nebulisation of undiluted fragrance oil; no water, no heat, no added humidity, no white mineral dust. Coverage up to 1000 m³, about 2,000–3,000 sq ft. 400ml refillable tank lasting roughly 90+ days at a mid setting. Bluetooth app plus onboard controls, 1h / 4h / 8h / 24h run windows, day selection, adjustable intensity, auto-stop and key-lock. Under 38 dB. DC 12V / 1A, 5W. Freestanding or wall / HVAC mount. CE, RoHS and SGS certified. SOSA does not currently sell a separate Vaayu cold-air refill oil; the 400ml supplied in the box is the fragrance available at the time of writing, so a practice planning continuous or multi-site use should confirm current refill availability with SOSA before committing. The water-based Hotel Collection is made for ultrasonic machines and must not be used in a Vaayu. Other machines: Boond 300ml ₹899 (~150 sq ft, ultrasonic) · Sukoon 500ml ₹1,899 (270–320 sq ft, 16–18 hours on low, remote and steady/2H/4H timers, three 15ml fragrances included, ultrasonic) · Megh 6L ₹3,499 (~215 sq ft — a runtime and humidity machine that covers less than a Sukoon, never a coverage upgrade) · Safar ₹3,999 (waterless cold diffusion, cordless, 20ml, about 6.9cm, three speeds, 1/2/3-hour auto-off — sold as a car and travel diffuser, personal-scale only; SOSA publishes no coverage figure for it) · Aangan ₹25,999 (HVAC nebulising, ~8,000–10,000 sq ft) · Meenar ₹38,500 (commercial HVAC, 12,000–18,000 sq ft). Water-based Hotel Collection for ultrasonic machines: 15ml ₹299 · 100ml ₹999 · 300ml ₹1,799 · pack of seven ₹1,799; scents are inspired by the atmosphere of well-known hotels — SOSA is an independent Indian brand and is not affiliated with, endorsed by or supplying any hotel group. Reed diffusers ₹749–₹1,349 (50ml 6–8 weeks, 130ml 14–18 weeks, six fibre reeds, no 100ml size; replacement reeds are not sold separately). Reed oil cannot be used in an ultrasonic machine and Hotel Collection oil cannot be used in reeds. SOSA sells no room spray or home spray — every SOSA spray is a car perfume. Nothing in this guide is medical, clinical or safety advice. A fragrance diffuser adds a scent to the air. It does not clean, purify, filter, sanitise or disinfect air, does not remove or neutralise disinfectant, damp or occupancy smells, and has no effect on comfort, anxiety, waiting time, recovery or any clinical outcome. Some people are sensitive to airborne fragrance, which is why this guide recommends that examination rooms, diagnostic areas, consultation cabins, procedure suites and post-operative areas remain fragrance-free, that a fragrance-free seating option always exist, and that a diffuser is never mounted into shared HVAC in a clinical building. Decisions about clinical policy, ventilation standards, infection control and patient suitability rest entirely with the practice and its clinicians. A persistent stale, damp or disinfectant smell is a ventilation, moisture or cleaning problem — SOSA sells no dehumidifier and no air purifier, and fragrance should never be used to cover one. Coverage, runtime and longevity figures are manufacturer specifications and typical ranges, not guarantees, and vary with room volume, ceiling height, air exchange, occupancy and season. SOSA publishes no commercial or bulk pricing, no corporate account, no annual maintenance contract, no installation service, no stated warranty term and no multi-location programme; warranty length, spare parts, servicing and app platform availability are unconfirmed, and larger or multi-site enquiries should go through the contact page before any commitment.
