Buying Guide: Bedroom Pre-Filters

Keep these points in mind before you buy.

What a pre-filter does

A pre-filter is the first layer. It catches hair, lint and large dust so the HEPA and carbon layers do not clog early.

Washable vs. replaceable

Blueair says its fabric pre-filter can be vacuumed and washed on a gentle, low-temperature cycle; Levoit’s Smoke Remover filter ships with two spare replaceable pre-filters.

Clean on a schedule

EPA says a dirty, overloaded filter will not work well. Check the pre-filter every few weeks and more often with pets, dust or smoke.

Pre-Filter Tips

Keep it working:

• Vacuum it every few weeks.
• Wash only if allowed.
• Dry fully before refitting.
• Replace when torn.
