Honeywell FC100A1029 Air Filter 16 x 25 x 4.5

SKU#: FC100A1029
List Price: $61.81 Sale Price: $41.99
Product Description

The FC100A series filter is a cardboard frame box style filter made up of a web of fibers (MERV 10). As air passes through the filter media, particulates such as dust, pollen, dander, mold, and bacteria collide with the fibers in the filter and become trapped. Meanwhile, the clean air is allowed to continue through your heating and cooling system and into your home.

Replacement Schedule The media filter must be replaced when pressure drop across the media filter reaches 0.5 in. w.c. (0.1 kPa), or at least annually. If the media air cleaner is installed downstream from an atomizing humidifier or if the installation includes both heating and cooling, more frequent replacement may be necessary. Clogged media must be replaced promptly to avoid restricting airflow and reducing efficiency of the heating/cooling system. Record the replacement date in the space provided on the replacement media filter.

Other Options Honeywell released the POPUP series media as an optional replacement for the FC100A series filters. This new media ships collapsed and a higher efficency (MERV 11) which expands into place with no tools required. The new POPUP style media is wider than the old FC100A series media and WILL NOT work on non-Honeywell air cleaners. If you are interested in the POPUP media click on the related product shown below for additional information.

The filter media is not cleanable and must be replaced a minimum of twice a year, once in the heating season and again in the cooling season. If your home only has heating, the filter must be replaced annually. Please note, if you have shedding pets, or live in a dusty environment, you will need to replace the filter media more often.

Honeywell merv air filter by Larry marcus (Edison Nj US)

On track is a great company fair prices fast delivery knowledgeable people. This filter is pretty good however please be warned it doesnít last 3 months. It clogs easy because it does its job but it does restrict air flow in furnace which led mine to burn out over temp sensor switch so change it out early or this may happen to you and itís not a cheap switch for Lennox furnace

Air Filter by Ron Ballou (Plano Te US)

I am not sure that now is the time to rate a product that has only been used for a few weeks. The filter I ordered for our furnace is now in and replaced one that must have been in for a long time. It was completely black and full of lint and dust. So far the new filter has been great. There is not as much dust on the furniture. We are renting this house and had just moved in when we ordered the new filter.

# one quality by Jacques Vergon (Glendale Ca US)

I received the filter on time, thank you. I didn't have difficulty to install it. I also love the price, let say... half price from the dealer her in the Valley. And I drove 60 miles to get it, no bill ,I pay cash. California its a rip off State. Check everything before moving in;no lie. If you let them, they screwed you more...;no lie. I will order from you again , next year or so. Thank you. Have a great Holidays and a wonderful 2014 year. Jacques

Was pleased to have the media come in such a small box. They work very well and thank you for your engineering.

Filter Media Order by Craig Taylor (Plano TX US)

The filter is very cleverly designed to fold up for shipment, and works well in the HVAC system. My only disappointment was the very long time between order placement and receipt of the order.
