Castle Filters One-Year HVAC Furnace Filter, MERV 6, 20x36x1, 1 Count (Pack of 1)

Patented Filter Technology: Castle Filters use 3 layers of ¼-inch open-celled foam, with a patented tacky center layer that catches dust like fly paper. Proudly made in USA - US patent #10,183,249 B2
MERV 6: The Super-Flow MERV 6 air filter is an alternative to traditional see-through woven fiberglass or washable filters. The air filter offers superior protection of your equipment and home while still allowing maximum air flow
AC Air Filter: Castle Filters have 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to collect more dust while letting the air pass through
Lasts One Year: The furnace filter holds up to 20 times more dust than a pleated filter. While pleated filters need to be replaced about once a month, the Castle Air Filter lasts one year which is 4-12x longer than the others
Save Energy and Lower Land Fill Contribution: Castle’s HVAC air filter helps you save energy with its advanced filtration technology and also helps in generating less waste as it need not be changed every month like a standard filter

True Blue Allergen 20x36x1 Air Filter , MERV 11, 4-Pack

CLEANER INDOOR AIR: The True Blue MERV 11 Pleated HVAC Furnace Air Filter is designed for residential use to improve and freshen indoor air quality by reducing airborne contaminants and intruding microscopic particles. This filter is compatible with almost any brand and is appropriate for use in air conditioners, furnaces, heat pumps and HVAC units.
TRAP AIRBORNE CONTAMINANTS: The True Blue Allergen Air Filter is rated as a MERV 11, meaning it can trap up to 79% of the particles sized 3.0-10.0 microns. This filter effectively reduces airborne allergens, including dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog.
DESIGNED FOR FAMILIES WITH PETS AND ALLERGIES: Better protect your indoor air with electrostatic charged media to improve and prolong filter performance by using static electricity to attract and trap smaller airborne particles. This technology outperforms 1-inch standard fiberglass home air filter models.
REPLACE EVERY 4 MONTHS: To maintain optimal filtration performance, change your home air filter at least every 4 months. Regularly replacing air filters can potentially prevent costly repairs and help reduce monthly energy use. A dirty air filter restricts air flow and forces your heating and cooling or HVAC system to work harder to keep your home at the desired temperature.
PROUDLY MADE IN THE USA: Each air filter is manufactured and assembled here in the USA. Replacing or installing the filter is quick and easy! Simply follow the instructions on the packaging. To ensure proper fit, measure your current air filter for the exact size and compare it to ours.
