TDS and AQI figures on this page are indicative planning ranges compiled from publicly reported patterns for this city — not live readings. Actual values vary by locality, borewell depth and season. Test your own supply with a TDS meter (around ₹300), and get a laboratory analysis if you suspect arsenic, fluoride, nitrate or iron.
If someone in the household has allergic rhinitis, asthma or a dust-mite allergy, an air purifier stops being a comfort purchase and becomes a symptom-management tool. In Kanpur, where AQI averages 180 and peaks near 380 on pm2.5 from tanneries and industry, the ambient load is already doing half the provocation before pollen or dander is added.
The specification that matters most is one almost nobody advertises: whether the system is sealed. A HEPA filter only helps if all the air is forced through it. In cheaper units, air leaks around the filter through gaps in the housing, which is why a unit with an impressive HEPA rating can still leave a room full of allergens. Look for a stated sealed-system design, and treat a well-fitted gasket as more valuable than a higher headline CADR.
Avoid ionisers and ozone-generating "purifiers" outright for this use case. Ozone is a respiratory irritant, and for an asthmatic household it can make symptoms worse rather than better. If a unit has an ioniser, confirm it can be switched off — and switch it off.
Placement and habit matter as much as hardware. Put the unit in the bedroom, run it continuously with the door shut, and pair it with mattress and pillow covers if dust mites are the trigger. Filter life in Kanpur will be a third to a half of the rated figure, and for allergy use in particular do not run filters past their life — a loaded filter is a reservoir, not a barrier.
Scored against Kanpur's air — an annual average near AQI 180 and winter peaks around 380.

H13 or better, in a housing designed so air cannot bypass the filter. This distinction — not the HEPA grade itself — is what separates units that control allergens from units that merely contain a HEPA filter.
Ozone is a respiratory irritant and a poor trade for an asthmatic household. If the unit has an ioniser it must be switchable, and it should stay off.
Allergy control is about running the unit all night, every night. Sleep-mode noise under about 30 dB is what makes that sustainable in a Kanpur bedroom.
A washable pre-filter catches hair, lint and large dust before they reach the HEPA layer, which extends the expensive filter's life considerably — worth having anywhere, and more so in a home with pets.
At a third to a half of the rated figure in Kanpur, a filter kept past its life stops helping and becomes a reservoir. For allergy use this matters more than in general-purpose use — put a reminder in your calendar.

Air purifiers have almost no service requirement beyond filters — which is precisely why the filter is the decision. In Kanpur, at an annual average of AQI 180, expect genuine filter life of a third to a half of the manufacturer's rating.
