Standard Size vs. Custom Size Filter
Generally speaking, the exact size of a filter is slightly smaller than the size on the label (nominal size) you order. The air filter industry has a loose set of standards by which filters are manufactured to a size that is actually smaller than the labeled size. This practice allows for the small variances in the way air handling equipment is manufactured.
The exact size will measure 3/8" less in the flat directions, and the filter will be 1/8" thinner than the nominal thickness. For instance, a 2" thick 20”x24” filter would actually measure 1-7/8" x 19-5/8" x 23-5/8".
Custom Sizes - If you need to order custom sized filters, it is always best to measure an existing filter that easily fits your application, send us those exact measurements. Our fabrication department will build the appropriately sized filters to match your specifications. Custom size filters are exact in size. If you order a 15” x 15” filter, you will receive a filter that is exactly 15” x 15”, so be sure your filter rack has a little more room to allow for a smooth fit. A 1” or 2” thick filter will still be 1/8” undersize even on an exact custom filter.
If you have any questions regarding the correct filter size for your application simply drop us an e-mail and we’ll step you through the process.
Will modifications need to be done to my AC units?
No equipment modifications are necessary to convert to Air-Care Electrostatic Filters. We carry a full range of standard sizes and if necessary we can custom manufacture a filter to your specific needs.
How do I replace my air filter?
Location: Most HVAC systems generally have the filter located as close to the blower unit as possible, in the cold air return duct. Remove the grill or box cover holding your filter in place.
Remove the dirty filter: Dispose of the dirty filter in a bag to contain the dirt.
Install: Install your new Air-Care Electrostatic Filter with the air flow arrow pointing toward the blower. Record the date. We recommend you clean your Air-Care Filter at least every 6 months, more often if you experience higher dust levels in your home due to changes in outside air, construction or dry weather.
How do I clean my Air-Care Filter?
1. Use a vacuum cleaner to remove any heavy buildup of dust and lint that may have accumulated.
2. Lay the filter flat and spray it with a cleaning agent on one side and then the other until the filter is soaked with the detergent. DO NOT use spray oils or any other chemical sprays on the filter as this will dramatically reduce the "static-electric" effect.
3. Lay the filter with the dirtiest side down or prop at angle against fence or outside wall and flush the detergent from the filter using a garden hose with a nozzle. Flush opposite to air flow. If laying flat, a 1" or 2" object should be placed under one side of the filter frame to allow room for the water and dirt to escape. Turn the filter over and repeat the same procedure.
4. Perform steps 2 and 3 until the filter is clean. If the filter is extremely soiled, it may be more convenient to use a car wash facility to remove all embedded dirt from the filter. Always lay the filter flat when using high pressure water for cleaning.
5. Shake excess water out of the filter and allow it to drip dry to the extent that it can be carried without dripping water.
IMPORTANT: Your filter should be cleaned regularly to maintain maximum air flow in the system.
How does an electrostatic filter work?
The electrostatic air filters manufactured by Air-Care utilize synthetic material which develops an electrostatic charge as friction is applied to the plastic fibers. In the filters case, air flowing through the filter provides the necessary friction. This can be demonstrated by rubbing the surface of the filter with a cloth briskly and placing the filter over light weight flakes of material such as tea leaves, or styrofoam chips. The small chips will be attracted to the filter surface and held there due to the charge that developed on the filter as a result of rubbing it. The electrostatic charge that is developed as air passes through the filter, increases the filters attraction to particles such as pollen, molds, and dust.
What size particles will the filter capture?
Air-Care Electrostatic Filters are especially effective in capturing particles sized 1 micron and larger. A micron is 1/25,000 of an inch. Some of the particles our filters are able to capture include dust, lint, pet dander, pollen, mold spores, dust mites, and skin flakes.
How is indoor air quality improved?
Air-Care Electrostatic Filters have a MERV 6-8 rating, the higher the MERV rating, the better the air filtration. This number can be used as a comparison to your existing air filters. Most disposable air filters have a MERV 2-6 rating.
Which way should the air flow?
A label on your Air-Care Electrostatic Filter identifies air flow direction for easy installation.
How long will my filter last?
Your Air-Care Electrostatic Filter has a Lifetime Warranty. Periodic cleaning is necessary to ensure proper operation and effectiveness of your HVAC system. This may well be the last AC filter you ever buy!
What if my filter arrives in damaged condition?
If your filter arrives damaged, we will file a claim with FEDEX and ship out a new filter to you. We just ask that you keep the damaged filter in case FEDEX requests to see it. FEDEX may request a digital photo.
