How to Save on Replacement Filters
These points help you choose the best affordable air purifier replacement filter.
Count the yearly cost
Check how many filters you need per year, not just the price of one. Multi-packs and compatible sets lower the yearly cost.
Genuine vs. compatible filters
Genuine filters guarantee fit and the maker’s rated performance. Compatible filters cost less, and many fit well, but quality varies; read recent reviews.
Buy multi-packs
Two-packs and six-packs lower the cost per filter and mean you always have a spare.
Clean the pre-filter
Vacuum or rinse washable pre-filters every few weeks, as the manual directs. A clean pre-filter keeps airflow up and helps the main filter last.
Match the model number first
Every purifier uses its own filter shape. Find the model number on the label and match it to the filter part number before you buy.
Ways to Make Filters Last
Stretch every filter:
- Vacuum the pre-filter monthly.
- Close windows on smoky days.
- Use auto mode at night.
- Change carbon sheets on time.
