Pollen, dust mite debris and pet dander are large particles that settle fast. An allergy purifier needs high pollen and dust CADR, a sealed HEPA filter and a place where you actually spend time.
HEPA filters do nothing for smell. Pet odor is gas, and only carbon removes it, so the purifiers here are ranked on the carbon they carry, not the airflow on the box.
Pet dander is a light particle that stays airborne; pet hair is a heavy one that clogs filters. A pet purifier needs high certified airflow for the first and a pre-filter built for the second.
Pollen, dust mite debris and dander are mostly large particles, which MERV 12 and 13 filters catch at 90% or more. Our top allergy pick is the Filtrete MPR 1500 (MERV 12).
Every 60 to 90 days is the usual guidance for 1-inch filters, and Filtrete says at least every 90. Pets, allergies, renovation and smoke shorten it; deep media cabinets lengthen it.
The Vital 200S-P is Levoit's pet-household purifier: the most certified airflow in Levoit's mid-range, a side inlet that keeps fur off the filter, and a rectangular body that fits against a wall.
The MinusA2 is the purifier you can hang on a wall. It is quiet, slim and lets you pick a filter for pets, odors or toxins. Its smoke CADR is Rabbit Air's own and smaller than its price suggests.
