The filter
True HEPA is the line that matters
For allergies, the filter grade is the whole game: true HEPA captures 99.97% of 0.3-micron particles — pollen, dander, dust mite debris. “HEPA-type” and “HEPA-like” are not the same spec. The filter column in our table comes from each manufacturer's own documentation.
The habit
Run it continuously, not when symptoms hit
Allergen load is continuous, so filtration should be too. A unit matched to your room size can run on a lower, quieter setting 24/7 and still cycle the air several times an hour — better than blasting a small unit only when you sneeze.
- Pet owners: place the unit where the pet sleeps — dander is heaviest at the source.
- Filter replacements: check each product page for the replacement schedule before buying.
