Commercial air purification goes wrong in two directions and both are expensive. Under-specification looks like a token purifier in a meeting room while the open-plan floor it was bought to reassure remains untouched. Over-specification looks like one unit per twenty seats, chosen from catalogue coverage figures, delivering a fraction of the claimed performance because the numbers were quoted at a fan speed nobody can work next to.

The correct approach starts with load and volume, not with product. What is the measured particulate load in each zone, what is the room volume, what infiltration rate does the building actually have, and what air-change rate are we targeting? Those four numbers give a required clean-air delivery rate per zone. Only then does it make sense to ask whether that CADR is best supplied by upgrading the air handling unit's filtration, by standalone units, or by a combination.

Very often the answer is the AHU. Where the HVAC system can accommodate the pressure drop, upgrading central filtration to MERV 13 or higher treats the whole floor for less capital and far less ongoing management than a fleet of individual machines with individually tracked filter schedules.

What's included in commercial air purification consultation

This is the scope we ask providers to quote against. Holding every quote to the same list is what makes them comparable — otherwise you are choosing the cheapest number rather than the best value.

Baseline measurement of particulate load, VOC and CO₂ zone by zone.
Room volume and infiltration assessment, so CADR is calculated rather than assumed.
Required CADR computed per zone against a target air-change rate.
AHU filtration upgrade evaluated first — pressure drop, fan capacity and energy impact assessed.
Standalone unit specification where central treatment cannot reach, with placement mapped.
Realistic-speed performance modelling rather than catalogue maximum-fan figures.
Noise assessment at the fan speeds the units will actually be run at.
Five-year total cost of ownership — hardware, filters, power, and servicing.
Vendor-neutral specification you can tender, plus an implementation and monitoring plan.

Not included

Equipment supply, though we will route your specification to suppliers for quotation.
HVAC modification and electrical work.
Ongoing monitoring, available as a separate service.

How CADR should actually be calculated

Required CADR in cubic metres per hour equals room volume multiplied by your target air changes per hour, adjusted upward for measured infiltration. For a general office, four to five air changes per hour is a reasonable target; for a clinical waiting area or a room with a known local source, six or more.

A 40-square-metre meeting room with a 3-metre ceiling is 120 cubic metres. At five air changes per hour, that is 600 m³/h of clean air — which is well above what most consumer-grade units deliver at a speed anyone can hold a meeting next to. This is the arithmetic that separates a specification from a purchase, and it is why catalogue coverage figures quoted in square feet mislead so consistently.

Note the two adjustments that matter in Indian buildings. Ceiling height is frequently above the 2.7 metres that coverage figures assume, which increases volume by 10-25%. And infiltration through non-sealed facades in older buildings can be high enough to require a materially larger CADR to hold a given indoor level against outdoor load.

Important

Manufacturer coverage figures are stated at maximum fan speed, where most units are between 55 and 65 dB. Nobody runs a purifier at that speed in an occupied office. Specify against the CADR available at a fan speed under about 45 dB, which is typically 40-60% of the headline number.

Central filtration versus standalone units

Central AHU upgrade: treats whole floors, no per-unit management, lower cost per square foot. Requires HVAC that can take the added pressure drop, and a fan with capacity in reserve.
Standalone units: no HVAC dependency, targeted at problem zones, movable. Higher cost per square foot at scale, and every unit is a separate filter schedule someone has to own.
Hybrid, which is the usual answer: AHU upgrade as the base layer, standalone units in the specific zones that still fail — ground floors near parking, spaces beside arterial roads, rooms with local sources.
In-duct UVGI on cooling coils: addresses microbial growth on coils rather than particulate. Worth evaluating separately in humid climates, not a substitute for filtration.
For clinical and isolation areas, requirements are set by the applicable healthcare standard rather than by comfort targets, and the design should follow that.

The running-cost model people skip

Over five years, filter replacement typically exceeds the hardware cost on a commercial purifier fleet — often substantially. A ₹35,000 unit consuming ₹6,000 of filters a year costs ₹65,000 over five years, and forty of them is a ₹26 lakh commitment that no one modelled when the ₹14 lakh purchase was approved.

This is why platform choice matters more than unit price. Filter cost per unit of CADR delivered, filter availability in India, and whether the model is likely to still be supported in four years are the variables that decide five-year cost. A slightly more expensive unit with cheaper, widely available filters is usually the better commercial decision.

Model power too. A fleet running twelve hours a day at moderate speed is a real electrical load, and it is one of the few facilities costs that scales linearly with the number of machines you were talked into.

What "verified" means

It is a specific claim, so here is exactly what it covers. Every provider on this network has:

Government photo ID and address verified at onboarding
Business registration or GST number on file where applicable
References checked from at least three completed jobs
Agreed to publish itemised pricing before starting work
Agreed to record input and output TDS on every service slip
Removed from the network after two unresolved customer complaints

Verification covers identity, registration and references. It is not a guarantee of workmanship on any individual job, and we are not a party to the contract between you and the provider — you engage and pay them directly. If a job goes wrong, tell us: providers are removed from the network after two unresolved complaints.

Commercial Air Purification Consultation — FAQs

How much does commercial air purification consultation cost?

₹10,000-₹25,000 for a single-floor office up to 5,000 sq ft, ₹25,000-₹50,000 for multi-floor buildings, and ₹50,000-₹75,000 for a campus or clinical facility. A vendor-neutral tender specification alone costs ₹10,000-₹30,000. The fee is usually a small fraction of what correct sizing saves against a catalogue-based purchase.

How many air purifiers does an office need?

It is calculated, not estimated. Required CADR per zone equals room volume times target air changes per hour, adjusted for measured infiltration — then divided by the CADR each unit actually delivers at a fan speed people can work beside, which is typically 40-60% of the catalogue figure. Very often the correct answer involves upgrading AHU filtration instead of buying most of the units.

Is central HVAC filtration better than standalone air purifiers?

Where the HVAC can take the pressure drop, yes — it treats whole floors at lower cost per square foot and with no per-unit filter management. Standalone units make sense for zones central treatment cannot reach effectively, and for buildings whose AHUs have no spare fan capacity. Most real designs are a hybrid of both.

Do air purifiers help with CO₂ in offices?

No. Purifiers recirculate and filter the same air; they do not remove CO₂. Rising CO₂ is a ventilation problem and needs fresh air — rebalanced dampers, demand-controlled ventilation, or heat recovery ventilators. This distinction matters because CO₂ is the most common finding in Indian office audits and purifiers are the most common proposed response to it.

Can you supply the equipment as well?

The consultation is deliberately vendor-neutral — you receive a specification you can tender, which is what keeps the sizing honest. We will route that specification to commercial suppliers in your city so you receive comparable quotations against the same requirement.

Which cities do you cover for commercial air purification consultation?

India's metro cities — Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Pune, Kolkata, Ahmedabad — plus the NCR and MMR satellites Gurugram, Noida, Ghaziabad, Faridabad, Thane, Navi Mumbai, which share the same technician supply pool. We publish a city only where we can genuinely route your request to providers who will call back, which is why the list is deliberately shorter than the 200 cities we cover editorially.

Is it free to get commercial air purification consultation quotes?

Yes. You pay the provider directly for the work they do, and never us for the introduction. There is no obligation to accept any quote and no cancellation charge, because nothing is committed until you engage a provider yourself.
