How To Choose the Best Furnace Filter for Your HVAC System

by Barbara 4. November 2015 04:56

Question: How do I choose a furnace filter for my HVAC system?

Answer: Always check with your HVAC technician prior to replacing your furnace filter. He or she is knowledgable about the air duct capacity and motor capacity of your system. Another option is to match the furnace filter in your system with another that is the same MERV rating or  MPR (Microparticle Performance Rating)‎. Explain that the 1 inch filter has an internal frame, that no air can go around it. Similarly the 4 inch thick unit is made to fit a 4 or 5 inch filter slot.

The buyer of a furnace filter must assume responsibility for his or her choice of furnace filters. No on-line company nor box store knows the age, the air duct capacity, the motor capacity, etc. of your HVAC system. Only your HVAC technician is qualified to determine the density of a filter that will work in your furnace and cause no problems.

Safe Home internal frame filters have two layers of media. The white side must be inserted into the filter panel so that the air flow goes through that part first. With the internal metal frame, this filter fits very tightly into the opening. No air can go around it. Your HVAC technician needs to know that this is an internal frame filter with no air escaping around it.

The Safe Home Duo 4 filters are also made to fit very tightly in the filter holder. This unit is also marked so it must be installed so that the air flow goes through the filter in the correct direction. Again it is important that your HVAC technician be aware of this tight fit. These units replace 4 or 5 inch thick filters. Always insert so that airflow goes first through the white side.

Thanks for your question.

HEPA Filter Cartridge on Amaircare 3000 Portable Air Purifier-How Often to Change the Filter?

by Barbara 12. July 2010 13:48

Question about the Amaircare HEPA Filter Air Purifier Model 3000.

Q: "How often should I change the HEPA filter in my Amaircare 3000 portable air cleaner? I have cats and dogs and use it in my bedroom because my husband is allergic. Thanks." Susan

Answer: Usually the HEPA is changed every 2 to 3 years depending upon where the air purifier is used. What is as important is to wipe off the outside of the metal cabinet regularly and to change the pre-filters and inner filters regularly. Typically the outer filter is changed every 3 to 4 months and the inner filter every 6 months. The outer filter is made from foam and can be washed with detergent and water. The inner filter is made from a pure carbon blanket media that removes VOC's (volatile organic compounds like formaldehyde, paint thinner, etc.) and is not washable.

Americair manufactures its own Amaircare® brand HEPA filters in Canada. Filament is bonded to air filter media for structural support and even pleat spacing. After pleating, filters are enclosed in protective screens and cast in food-grade plastisol at both ends for a 100% air seal. 100 square feet of HEPA filtration material captures the smallest particulates. Each Amaircare HEPA filter is then tested for 99.97% efficiency, with a laser particle counter.

The Amaircare 3000 HEPA filter is a 16 inch cartridge filter that also fits the Amaircare 3050 and and Amaircare 4000. (These units are no longer made.) The same intervals should be followed for the other Amaircare air purifiers which include the Amaircare 2500 and the Roomaid with the VOC canister filter or with the standard HEPA and pre- and post-filters. There are also VOC cartridge filters that can be added to all these air purifiers.

Important: Always replace a HEPA air filter if an air purifier is turned off for more than 3 to 5 days. HEPA is a medium in which bacteria, viruses, etc. can grow if moisture collects in the filter media. Constant air flow keeps the HEPA filter media dry and free of such contaminants. I confess that I take my canister vacuum cleaner into the bedroom, remove the outer filter, lay it on the floor and vacuum it off with the floor tool every few weeks. We have two Boston Terriers  and two cats so the dust raised is incredible. I wipe out the interior with a microfiber cloth.

Thank you for your question.
