Buying Guide: When and How to Replace Filters
Keep these points in mind before you buy.
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.
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.
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.
A washable pre-filter helps
A pre-filter catches hair, lint and large dust before the HEPA filter. Vacuum or rinse it every few weeks, as the manual directs, so the main filter lasts longer.
Swap Your Filter Right
A clean 4-step swap:
- Unplug the purifier.
- Bag the old filter outside.
- Remove all wrapping.
- Reset the indicator.
