- Is a MERV 8 filter enough for allergies?
- It captures pollen, dust, lint and pet hair, which helps most households. For fine smoke or serious allergy control, a MERV 11 to 13 pleated filter captures more.
- How often should I wash it?
- Check it monthly and rinse when it looks loaded, typically every one to three months. Let it dry completely before putting it back.
- Will it fit my furnace?
- It is sized 20 x 25 x 5 in, a common cabinet size. Measure your existing filter slot before buying, since the depth matters.
- Does washing ruin the electrostatic charge?
- The charge weakens gradually with repeated washing. Gentle rinsing and full drying help it last longer.
- Is it better than a disposable filter?
- It wins on long-term cost and waste. Disposable pleated filters win on filtration if you need higher MERV.
- What is in the box?
- One washable electrostatic filter. No frame or accessories are included.
