Lasts up to 12 months Air Filter Depth (in.): Filter Performance Rating (FPR): Air Filter Height (in.): Air Filter Width (in.): 7 Some filters say 20 x 25 x 4 , some 20 x 25 x 1 and some are 20 x 25 . What is the thickness of the 20 x 25s ? Im looking to purchase a case of 20 x 25 x 4s. I don't see that item. Unless its the 20 x 25 case in Honeywell. 6 Does Honeywell recommend using a MERV 12 filter if the system came with a MERV 10 filter? 5 Is the 2 pack for $39.77 or is it just for one item? I see that one item of a different size is also $39.00 for one.So I guess, what I am asking is do I get both for the one price. 5 Will these work in a Westinghouse unit as well?

I realize that the brand is Honeywell, but my heat pump is a Westinghouse. All of the specifications of the filter seem to be very similar (size of filter and filtration of allergens, viruses, et al.) to those of the one from my unit, so I just wanted to see if these filters would work for the Westinghouse as well. I attached a picture of a filter that works for my unit, although the picture shows a different size than my 20x25x4.Shipping and handling charges are FREE. 20 in. x 25 in. x 5 in. Replacement Filter for Trion Air Bear Air Cleaner 36% more filter material compared to other brands Long lasting filter, lasting up to a year MERV RATING: 11 - FPR "Filter Performance Rating": 6 - Specifically Designed to Fit: Trion Air Bear 435790-027, 53 times more effective than fiberglass filters and will last up to 1 year. Filters are assembled with a heavy duty frame that prevents collapsing of the filter during installation. 36% More Filter Material Compared to Other Brands.

During the manufacturing process, we charge the filter media with an electric current. This process allows the filter to attract very small particles much the same way magnets attract metal. The end result is a far more effective filter. The Electrostatically Charged filter media filters sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog. bionaire air purifier 706100% Synthetic filter media will not support the growth of Bacteria, Mold, or Fungi in normal use.rainmaker air cleaner Specifically designed to fit: trion air bear 435790-027a.n.t. global air duct cleaning reviews Reduces dust and dirt buildup in air ducts and in air conditioner and furnace system

Generally speaking, a higher MERV rating indicates better filter performance. Media for Aprilaire Air Cleaners These are the original, OEM expandable "accordian" style, factory recommended replacement filters. This is the high efficiency filtering media, which is the heart of your air cleaner. It will last from one to two years depending on the operation of your heating and/or air conditioning system. In any application, the life of the media is dependent upon the total volume of air being moved through it as well as the amount of particulate it is filtering. These filters fit the GeneralAire AC-1 & AC-3 the Carrier 31MF020100 and Bryant 902BXX020. Generalaire recommends that the filter be replaced every 6 months. GENUINE OEM Five Seasons MERV (Minimum Efficiency Reporting Values). It is a number from a test method designed by ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) The number is intended to help people compare filters.

As a rule, a higher MERV rating indicates better filter performance. Our high-efficiency, charged postfilters boost the efficiency of any Honeywell electronic air cleaner with negligible effect on pressure drop. Clean the pre-filters regularly - every 1 to 6 months Original Honeywell MERV 10 Factory Replacement Filter Ultra-Web technology is exclusive to high-efficiency Honeywell Media Air Cleaners. Media air filters, at the microscopic level, consist of an interlocking network of fibers that appear quite porous. This porosity is necessary to allow air to pass through the unit with minimal pressure drop. The interlocking fibers of the Ultra-Web material form a web that captures particles that pass right through them. The particles are captured three different ways: For optimum system performance, replace the filter every six months (before heating season and before cooling season). Adjust the schedule to your needs, but replace the filter at least annually. Honeywell's MERV 13 higher efficiency replacement media is a charged filter media for improved performance that helps keep an HVAC system clean for up to a year, while filtering out some of the smallest particles.
