What is the biggest mistake people make trying to keep a large home low-maintenance? Buying several small machines instead of sizing one to the actual air volume. Multiple Vaayu units scattered through a large home each need their own schedule, their own refill and their own intensity check, which is more maintenance, not less - one Angaan on the HVAC does the same job with a single schedule and a single monthly refill.
How often does a low-maintenance routine need attention? About once a month, to check the reservoir level - an 800ml Angaan reservoir or a 400ml Vaayu tank lasting up to 75 days. The daily schedule itself, once set on the Bluetooth app or programmable schedule, needs no further attention between refills.

Low-maintenance in a large home is not about buying more machines - it is about buying fewer, sizing them properly, and setting one schedule you never have to think about again. Here is the whole routine in one page.

Straight answer
What is the lowest-maintenance way to keep fragrance consistent across a large luxury home?
The lowest-maintenance routine for a large home is almost always fewer machines, not more. One SOSA Angaan (₹25,999) mounted on the home's central HVAC uses the airflow the building already moves, carrying one fragrance evenly across up to 3,000m³ - roughly 8,000 to 10,000 sq ft - from a single point. That single point is also the single thing that ever needs attention: one schedule, set once, and one 800ml reservoir to check, rather than five or six small machines each with their own timer and their own refill date to remember. Set a fixed two-entry daily schedule - a morning window and an evening window, both at a modest, unchanging intensity - on the Angaan's programmable schedule, and leave it alone between refills. Vaayu and Angaan are not connected to your smart-home system. There is no wifi, no cloud account, no Alexa or Google Home skill, and no Control4, Crestron, Lutron, KNX, Matter, Zigbee or Z-Wave integration. What they do have is a repeating clock-based schedule, set once on the machine's own Bluetooth app, that runs every day with nobody touching it. The honest exception is a detached wing, guest cottage or separate structure the central HVAC genuinely does not reach - that gets its own SOSA Vaayu (₹11,999) on the same two-entry pattern, rather than trying to force one system to cover a building it is not physically connected to. Check the reservoir roughly once a month; between checks, the routine needs nothing from anyone. A portion of every order supports girl-child education through Nanhi Kali.
One Angaan on the central HVAC, one fixed two-entry schedule, one monthly reservoir check. A Vaayu only for a wing the HVAC cannot reach.
The SOSA Angaan mounts on the home's central HVAC and carries one fragrance across up to 3,000m³ from a single point - one schedule, one 800ml reservoir, checked monthly. Under 42dB. ₹25,999.

The three decisions that make a large home's routine low-maintenance
Three decisions determine whether a large home's fragrance routine stays low-maintenance or quietly becomes a monthly chore.
1
One machine on the HVAC, not several small ones
Fewer machines means fewer schedules and fewer refills to track
The instinct to buy a Vaayu for every large room feels thorough, but it multiplies the maintenance: five machines means five schedules, five intensity settings and five refill dates. One Angaan on the central HVAC does the equivalent job across up to 3,000m³ from a single point, with a single schedule and a single reservoir to check.
Tip: count refill dates you would have to track, not rooms you want scented - that is the real maintenance cost.
The Angaan's 800ml reservoir and metal body are built for exactly this whole-home, single-point role.
See SOSA Angaan →
2
A fixed two-entry schedule, set once
Morning and evening, at a modest fixed intensity, never adjusted daily
Set a morning entry and an evening entry on the Angaan's programmable schedule, at a fixed, modest intensity, and do not touch it day to day. A routine that gets manually adjusted is not actually low-maintenance, even on an automated machine - the goal is a schedule nobody has to think about between refill checks.
A detached wing outside the HVAC's reach gets its own Vaayu on the same two-entry, fixed-intensity pattern, so the whole property behaves consistently.
See SOSA Vaayu →
3
One monthly check, nothing in between
The reservoir is the only thing that ever needs attention
With the schedule fixed and the machine sized correctly, the only recurring task is checking the 800ml Angaan reservoir, or the 400ml Vaayu tank lasting up to 75 days, roughly once a month. Between checks, the routine runs itself completely - no daily adjustment, no remembering to switch anything on or off.
Tip: put the refill check on the same monthly calendar reminder as the HVAC filter - it is the same kind of task.
The Angaan's 800ml reservoir is sized for a large home's air volume so this check stays monthly, not weekly.
See SOSA Angaan →
The SOSA principle
Low-maintenance is not a feature of the machine. It is a consequence of sizing correctly, so there is only one schedule and one refill to ever think about.
The fastest way to make a large home high-maintenance is to buy several small machines instead of one machine sized to the actual air volume.
One Angaan for the whole home, Vaayu only for what the HVAC misses
The decision is about air volume and HVAC reach, not about preference - a home on central HVAC almost always wants one Angaan first, with a Vaayu only for what the HVAC does not cover.

Keep the fragrance itself equally low-maintenance: one clean, restrained profile - light woods, soft citrus, white tea - across the whole home, rather than different scents per zone that each need tracking separately. For the underlying hours discipline this schedule should sit inside, see how many hours a day automated home fragrance should run, and for how to keep a large, low-touch routine from quietly over-scenting itself, see how to prevent an automated home from becoming over-fragranced.
One machine, one schedule, one monthly check
SOSA Angaan ₹25,999 - covers up to 3,000m³ on your home's central HVAC.

One honest note: adding more small machines to "cover everything" is usually what turns a routine high-maintenance, not low. Size one Angaan to the home's central HVAC first, and add a Vaayu only where the HVAC genuinely cannot reach.

A note from Sonal
The clients happiest with their scenting a year in are almost never the ones with the most machines - they are the ones with the fewest, sized properly. A large home tempts people toward one unit per room, and every extra unit is one more schedule, one more refill date, one more thing to eventually forget.
My standard recommendation for a large luxury home is one Angaan on the central HVAC, covering the whole footprint from a single point with a single fixed schedule. The only genuine exception is a wing or structure the HVAC does not physically reach, which gets its own Vaayu rather than forcing one system to do a job it is not connected to.
After that, the only task is a monthly check of the reservoir - I tell clients to put it on the same calendar reminder as the HVAC filter change, since it is the same category of task and just as easy to forget otherwise. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do I create a low-maintenance fragrance routine for a large luxury home?
Use one SOSA Angaan (Rs 25,999) on the home's central HVAC rather than several small machines, set a fixed two-entry daily schedule once, and check the 800ml reservoir about once a month. Add a SOSA Vaayu (Rs 11,999) only for a wing the HVAC does not reach.
Is it more low-maintenance to have one machine per room in a large home?
No, the opposite. Each additional small machine adds its own schedule, intensity setting and refill date to track. One Angaan sized to the whole home's HVAC reduces that to a single schedule and a single reservoir.
How often does the routine actually need attention?
About once a month, to check the reservoir level. The daily schedule itself, once set on the Bluetooth app or programmable schedule, runs on its own between refill checks and needs no daily adjustment.
What if my large home does not have central HVAC to mount the Angaan on?
Use one SOSA Vaayu per genuinely separate air volume instead. It will mean more than one machine, but each still holds its own fixed, low-touch schedule rather than needing daily attention.
Should different rooms in a large home have different fragrances to feel special?
For low maintenance, no - one consistent, restrained profile across the whole home is easier to manage and reads as more considered than several scents that each need separate tracking and refilling.
