Customer Reviews For The Honeywell 18x20x1 High Efficiency Allergen MERV 11 Air Filter, 4 Pack
Overall Rating
Product Reviews
These are good filters if you want to take many impurities out of the air. Just be careful and change them more frequently or else it will make your system work harder and can damage it.
Good price
For some reason, this size filter is hard to come by in the stores. I didn't even know that they could be ordered manufacturer direct. I was extremely pleased with the ordering process, price, and delivery time. Needless to say, I will be ordering directly from Honeywell in the future!
Product FAQs
A MERV 11 rating (Minimum Efficiency Reporting Value) indicates a superior level of filtration for residential homes. These filters are electrostatically charged to capture a high percentage of airborne particles between 1.0 and 3.0 microns, including:
- Dust, lint, and pollen
- Dust mite debris and mold spores
- Pet dander and bacteria
- Most smoke and microscopic allergens
Each filter in this pack is designed to last up to 3 months. Since this is a 4-pack, one purchase provides a full year of air filtration for a single HVAC system. If you have pets, nearby construction, or severe allergies, you may want to check the filter monthly and replace it sooner if it appears heavily soiled.
These Honeywell High Efficiency Allergen Filters are made in the USA. They feature a heavy-duty frame to ensure durability and a secure fit within your HVAC system’s filter slot, preventing "air bypass" where unfiltered air leaks around the edges.
