Frequently Asked Questions
What does MPR 700 / MERV 8 mean for airflow?
MPR 700 (roughly equivalent to MERV 8) captures common airborne particles like pollen, dust and pet dander without the heavier airflow restriction of higher-MERV filters. It’s a good middle ground for homes that need filtration but have HVAC systems that can’t handle high pressure drop.
How often should I change a 1-inch pleated Filtrete filter?
These are designed as 3-month filters under normal conditions. Replace more often (every 1–2 months) if you have pets, smokers, heavy dust, or allergy sufferers to maintain airflow and capture efficiency.
Will a higher-rated filter reduce my HVAC efficiency?
Extremely high MERV filters can increase pressure drop and reduce system efficiency if your blower isn’t designed for them. The MPR 700/MERV 8 filters reviewed here are chosen to limit airflow impact while still improving air quality. Always confirm compatibility with your HVAC manufacturer.
