Buying Guide: Choosing a Replacement Filter

Keep these points in mind before you buy.

Match the model number

Every purifier uses its own filter shape. Find the model on the label and match the filter part number before ordering.

Filter finder table for the best air purifier for allergies replacement filter
Match the part number to your model.

Genuine vs. compatible filters

Genuine filters keep the rated CADR and fit. Compatible filters cost less and many work well, but quality varies, so read recent reviews.

True HEPA vs. HEPA-type

True HEPA captures at least 99.97% of 0.3-micron particles, the size that is hardest to catch. Pollen, dust mite debris and pet dander are larger, so a true HEPA filter traps them well. Avoid vague HEPA-type claims.

When to replace filters

Most HEPA filters last about 6–12 months; pre-filters and carbon layers need attention more often. Heavy pollen seasons, pets and 24/7 use shorten filter life.

Before You Order a Filter

Avoid the wrong part:

  • Check the model label.
  • Match the filter part number.
  • Prefer genuine for allergies.
  • Note the install date.
