FFM11 Air Filter - MERV 11 - Specification Data Sheet

The 1" Air Filters MERV 11 -Case of 6 Filters (Better) is an economical alternative if you're looking for a quality air filter without paying a premium price. FiltersFast home air filters come in a variety of sizes and are a cost effective upgrade from simple fiberglass or poly pleated filters.

The FiltersFast MERV 11 air filter is equivalent to the Dupont Gold, Dupont Platinum, Dupont Maximum Allergen, Dupont ProClear Allergen Air filters, Filtrete Ultra Allergen Filters and many other top name brands and is available at a fraction of the cost.

These 1" air filters filters are available in both a MERV 8 and MERV 11 rating. MERV, or Minimum Efficiency Reporting Value, indicates when a filter will be least efficient. Higher MERV ratings indicate more efficient filters. Most fiberglass spun filters, such as those found in your local grocery store, are usually only a MERV 1 or MERV 2, which can affect the efficiency and air flow of your heating and cooling system, causing it to work harder to produce the same air flow and costing you more money!

These MERV 11 filters effectively reduce pollen, dust, pet dander, mold spores, dust mites and other allergens from your indoor air. Removing these airborne particles can help improve allergies and alleviate sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. The MERV 11 filter media is electrostatically charged and constructed with spun micro-fiber that also will not retain moisture, which can lead to microbial growth. Aside from the health benefits, these HVAC filters will also extend the life of your heating and cooling system by making it work more efficiently.

1" Air Filters Merv 11 -Case of 6 Filters (Better) Specifications:

• 6 pack
• Replace filter every 1 to 3 months
• Improves indoor air quality and alleviates allergy symptoms
• Reduces pollen, dust, pet dander, mold spores, dust mites and other allergens

These HVAC filters feature 18 pleats per linear foot for greater surface area to catch airborne particles. These allergy air filters should be changed every 1 to 3 months for optimum performance.

Prices listed are for a 6-pack of filters. For most homes, this is a year's supply -- and at a GREAT value!

Please note that FiltersFast Air Filters sizes listed are nominal sizes. The actual size of the filter will be smaller than indicated. For example, if you select a 25x25x1 air filter the actual size of the air filter you will receive will be 24.75x24.75x.75. Listing nominal size instead of actual size is an industry standard for most air filter brands, so if your current filter says 25x25x1, in most cases, this will be a nominal size. In some older homes, and in other cases, you may require the actual size. If you require the actual size you will need to place a custom order with a representative. If you are unsure whether you need actual or nominal size simply measure your air filter before placing your order.

The chart below will show you what you can remove with a MERV 13 air filter, a MERV 11 air filter, or a MERV 8 air filter.
