Frequently Asked Questions
Will a MERV 8 filter harm my AC efficiency?
No — MERV 8 is a good compromise for most residential systems. It improves indoor air quality without the high pressure drop of higher MERV ratings. Choose a pleated design sized correctly for your slot to avoid added strain.
Are washable metal filters as effective as disposable pleated filters?
Washable aluminum electrostatic filters can be effective and cost‑saving, but their performance depends on fit and cleaning frequency. They generally capture larger particles well; disposables often perform better for very fine particulate capture out of the box.
How often should I change or clean these filters?
For 1‑inch pleated disposables plan on changing every 30–90 days depending on pets and dust levels. Reusable washable filters should be rinsed and fully dried every 1–3 months. Increase frequency in high dust or allergy seasons.
