Performance Data
Effective Filtration Without Unnecessary Airflow Restriction
Filtration always adds resistance. EverFilter is engineered to minimize it while capturing particles over time.
Chart shown represents clean filter performance under controlled airflow conditions.
What Circulates Through Homes Over Time
The visuals below illustrate common types of airborne particles often found in residential indoor environments. During normal HVAC operation, air moves continuously through the home, carrying particles that circulate with airflow rather than remaining in one location.
EverFilter is engineered to capture airborne particles over time while maintaining airflow, allowing filtration to occur consistently without unnecessary pressure drop.
Visual representations shown for educational purposes. Actual indoor air conditions vary by home.
How EverFilter Compares to Traditional Filter Types
Low-MERV Fiberglass Filters
MERV 1-4 · Minimal resistance, limited protection
- Captures large debris like lint and visible dust
- Very low airflow resistance when clean
- Minimal particle capture beyond large contaminants
- Media collapses easily under higher airflow
- Offers little system or indoor air protection
- Short service life and frequent replacement
Best for: Basic protection only where airflow is the sole priority
Washable Electrostatic Air Filter
Balanced airflow and reusable filtration for long-term system protection
- Captures lint, dust, and airborne particles
- High-loft fiber web allows efficient filtration with low resistance
- Designed for consistent airflow throughout service life
- 30-90 day media replacement interval
- Reusable frame system reduces long-term cost
- Compatible with optional carbon insert for odor control
Best for: Homeowners who want real filtration without restricting their HVAC system
Disposable Pleated Filters
MERV 8-13 · Designed for one-time use
- Airflow decreases as pleats clog
- Increased blower motor strain over time
- Creates cardboard, metal, and plastic waste
- Easily bent or damaged during installation
- Can collapse or be pulled into system under pressure
- Higher long-term replacement cost
Best for: Situations requiring high-MERV capture where airflow impact is acceptable

Product Questions & Answers
How do I choose the right size?
EverFilter
Select your filter's nominal size (the size printed on your old filter). If you're between sizes, choose Custom Size for a perfect fit.
Choose your size above to get started.
What's the difference between nominal and exact size?
EverFilter
Nominal is the label size (like 20×20×1). Exact is the real measured size, usually slightly smaller. we subtract 1/4" on Length and Width. Use nominal unless your slot is unusually tight.
If it's tight, pick Custom Size and enter exact measurements.
My filter slot is tight. Will the aluminum frame fit?
EverFilter
Yes, it's designed for a snug seal. If your slot runs extra tight, we can exchange for a slightly smaller frame so it slides in smoothly.
Tap Custom Size if you want the safest fit.
Will this restrict airflow like pleated filters?
EverFilter
EverFilter uses high-loft media built to capture airborne contaminants while keeping airflow high. It's a smart balance for most homes.
Why does airflow matter so much?
EverFilter
Restricted airflow can increase run time and strain equipment. EverFilter is designed to keep filtration strong without stressing your system further.
Select your size and lock in high airflow.
What comes in the Starter Kit?
EverFilter
Your Starter Kit includes the reusable aluminum frame plus 6 high-airflow MERV 8 media pads (ready to install).
What media is included?
EverFilter
High-loft MERV 8 antimicrobial tackified polyester. The blue air-exit side is tackified to improve capture while maintaining airflow.
Choose 1" or 2" thickness to match your slot.
How long do the pads last?
EverFilter
Most homes replace every 30–90 days depending on pets, allergies, renovations, and runtime. Replace when the pad darkens to maintain optimal HVAC efficiency.
Add a Refill Pack so you don't forget later.
How do I replace the media pad?
EverFilter
Slide out the frame, remove the used pad, secure a fresh pad into the frames edges, and reinstall. No tools.
Can I rinse or reuse the pad?
EverFilter
The aluminum frame is reusable. The media pads are designed to be replaced every 30-90 days.
How fast do you ship?
EverFilter
Most orders ship within 1 business day. Typical delivery is 2–5 business days depending on location. We ship from Florida, USA
What if I ordered the wrong size?
EverFilter
Message us and we'll help you dial it in. We can assist with an exchange so you end up with the right fit.
If you're unsure, choose Custom Size.
Customer Reviews
Filters twice what paper does and lasts much longer.
Replaced a washable metal mesh filter that never felt clean. After two months, these are clearly a better solution.
Ordered a full year supply. Great quality material at a phenomenal price. Will reorder. Fast shipping.
Switched my parents from disposable paper filters. Easy to replace and captures dust well. No debris in ductwork. Highly recommend.
Cardboard filters kept getting sucked into the air handler. This stays in place, filters well, and is reusable. Saves money over time.
Massive airflow improvement. During 100+ degree weather, the AC finally kept up. Highly recommend.
Exact fit solved years of issues with filters collapsing or not fitting. Aluminum frame slides in easily. Worth every penny.
Well made and works perfectly. My husband has been in HVAC for 25 years and these are his favorite.
Very efficient filter. Air in the house is noticeably cleaner without straining the heat pump.
