Six things, in the order you will need them

Six things cover almost all of it, and they are worth having in the order you will actually need them rather than in order of interest, because the interesting one comes last. One: fix the sources first. This is the rule that outranks everything else in the category and it is the one most often skipped. Fragrance does not mask an existing smell - it combines with it, and the combination is consistently worse than either component alone, and it reads unmistakably as a house hiding something. So cooking that drifts from a kitchen with inadequate extraction, monsoon damp, drains and dry traps in unused bathrooms, musty rugs and cane furniture, a store sealed since completion, and a fit-out still off-gassing paint, sealers, adhesives and engineered board all come before any product decision. If any of those are present, the specification is extraction, dehumidification, cleaning or time, and fragrance comes afterwards as the finishing layer. Saying that to a client is also the fastest way to be believed about everything else you recommend. Two: read the doors, not the floor area. A machine distributes fragrance through connected moving air and cannot cross a closed door, so a home divides into zones bounded by the doors that are normally shut, and the number of those zones - not the square footage - decides the specification. Mark every normally closed door on the plan and the answer appears: each connected zone takes one machine, and each closed room takes a reed. A typical four-bedroom home is one machine and eight to twelve reeds; a large villa might be one machine and fourteen. It also means the honest answer to a client whose fragrance does not reach the back bedroom is a reed in that room rather than a larger machine, because a bigger machine still cannot cross a closed door. And it means the electrical drawing needs very little: one socket per connected volume, at console height, because reeds need no power at all. Three: spend at two positions. The entrance and the guest bathroom are the only two places in a home where fragrance is read by an unadapted nose. Everybody adapts to a steady background within about an hour, so the family cannot smell their own house and a guest twenty minutes into the living room has largely stopped reading it - the only unadapted nose in a building is the one that has just come in from outside, and the only room that resets an adapted nose on every entry is a small enclosed one entered from another room's air. Those two positions produce more of the effect a client is describing than the rest of the house combined, and both are served by reeds at Rs 749 to Rs 849, three to four months a bottle, refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml, roughly Rs 200 to Rs 280 per room per month. If a budget stretches to two things, those are the two. Four: set the level by rule rather than by nose. This is what decides whether a scheme succeeds or quietly embarrasses you. Because everybody adapts within about an hour, a household setting the level by smell will turn it up, stop noticing, and turn it up again - the input to the decision is a sensation that always fades, so the system only ever climbs, ending in a house visitors find strong and the family cannot detect at all. Set it low, run it continuously rather than in strong bursts, and give the client a written rule: leave it alone, and adjust only if somebody who does not live there remarks on it, because a remark means it is above the line. Set intensity inversely to exposure time - an entrance can carry the most because nobody stays in it, a living room takes a moderate level set for the family rather than the visitor, and a master bedroom takes the lowest in the house because it is eight unbroken hours for two people who cannot leave. Five: choose the register last, and choose the plain one. It is the cheapest and most reversible decision in the whole layer - a bottle from Rs 299 for 15ml, Rs 999 for 100ml or Rs 1,799 for 300ml, swapped in a minute - which is why it should not consume the attention. Bring three options you can defend and let the client choose between them, the same division you already use with fabric: you hold the technical constraint and they hold the preference. Quiet Luxury, with white tea, bergamot and cedar, is the safe centre and has enough structure to register as something without being identifiable. Forest Suite, with cedarwood, vetiver and green leaves, suits a material-led scheme. White Tea Serenity, with white tea, aloe and cedar, is the softest. And resist the instinct towards something distinctive, because a fragrance a guest can name has become a thing in the room rather than a quality of it. One register throughout the home, varied by intensity rather than by scent, because two registers meet in doorways many times a day and the collision reads as something being slightly wrong. The seven Hotel Collection registers are SOSA's own interpretations, and we are independent and not affiliated with, endorsed by or associated with any hotel brand. Six: write it down. A handover pack is what keeps this working after you have gone, and its job is to remove decisions so the client never has to make one. It should carry the register and where each item sits room by room, because objects migrate; the level and schedule you set; the correction rule; the machine instruction - water-based Hotel Collection only, three to six drops per tank, rinse between scents, never reed oil, which can damage a machine; and the reorder path, because reeds are consumed by time rather than by use and month four is when an unattended scheme quietly stops working. A layer that died is remembered as having died, which is worse for a practice than one never specified. Write the exclusions in as excluded rather than absent, too: never the kitchen at any time, because cooking smell is aerosolised oil and the answer is extraction; no fragrance in children's rooms; a covered terrace, balcony or verandah cannot hold fragrance because the air is not enclosed, and a larger machine does not change the physics; nothing in staff quarters or utility areas. And add the consent line: anybody who shares the home and cannot leave a room they did not choose the scent for gets a low neutral register and a physical off switch, not an app-only one, that they never have to justify using. On systems, the plan decides: the Vaayu at Rs 11,999 for a large connected volume, waterless with no tank, coverage up to 1,000 square metres or roughly 10,700 square feet, with Bluetooth app and timer control; the Megh at Rs 3,499 with a 6L tank; the Sukoon at Rs 1,799 for a single room; the Boond at Rs 799 for a small one; and reeds behind every closed door. Two last things. Raise this at specification stage rather than at handover, because at the end it has the shape of an object being sold and in the schedule beside lighting and ironmongery it is a layer being drawn. And make no claim that fragrance affects mood, focus, sleep, stress or wellbeing - we make none, and a proposal that does is a liability rather than a selling point. Everything is alcohol-free and made to IFRA-compliant standards, and a portion of every order supports girl-child education through Nanhi Kali. Volume pricing across a project is quoted against the specification on WhatsApp.

Everything that matters, once

Six things, in the order you will need them. Fix the sources first, because fragrance combines with an existing smell rather than masking it and the combination is worse than either alone - cooking from inadequate extraction, monsoon damp, drains and dry traps, musty rugs and cane, a sealed store, a fit-out still off-gassing. If any are present the specification is extraction, dehumidification, cleaning or time, and fragrance follows. Read the doors, not the floor area: a machine cannot cross a closed door, so the number of separated zones decides everything - each connected zone one machine, each closed room a reed, which makes a four-bedroom home one machine and eight to twelve reeds, and means the answer to an unreached bedroom is a reed rather than a bigger machine. It also means one socket per connected volume at console height, because reeds need no power. Spend at two positions: the entrance and the guest bathroom, the only places read by an unadapted nose, since everybody adapts within about an hour - together they beat the rest of the house, both reeds at Rs 749 to Rs 849, three to four months a bottle, roughly Rs 200 to Rs 280 per room per month. Set the level by rule rather than by nose, because anybody adjusting by smell climbs forever, the input being a sensation that always fades - low, continuous, corrected only on an outsider's remark - with intensity inverse to exposure: entrance highest, living room moderate and set for the family, master bedroom lowest at eight unbroken hours for two people who cannot leave. Choose the register last and choose the plain one: it is the cheapest and most reversible decision, from Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, so bring three you can defend and let the client pick - Quiet Luxury as the safe centre, Forest Suite for a material-led scheme, White Tea Serenity as the softest - and resist distinctiveness, because a nameable fragrance has become a thing in the room. One register throughout, varied by intensity. And write it down: locations room by room since objects migrate, the level and schedule, the correction rule, the machine instruction - Hotel Collection only, three to six drops, never reed oil - and the reorder path, because month four is when an unattended scheme dies and a layer that died is remembered as having died. Write the exclusions in as excluded: never the kitchen, nothing in children's rooms, no covered terrace, nothing in staff or utility areas, plus a physical off switch for anyone who cannot leave. Systems: the SOSA Vaayu at Rs 11,999 with coverage to 1,000 m², SOSA Megh at Rs 3,499, SOSA Sukoon at Rs 1,799, SOSA Boond at Rs 799. Raise it at specification stage rather than handover, and make no claim about mood, focus, sleep, stress or wellbeing. Everything is alcohol-free and made to IFRA-compliant standards. Volume pricing is quoted on WhatsApp.
