Home Air Filters: What You Need to Know About Air Filter Simplified

We are going give you a simple way to pick the right air filter for your home because choosing  the best air conditioner filter for your allergies can sometime be a confusing task. The simple reason is that most people are not experts on their  heating and air conditioning systems and generally rely on the recommendation of the company that services their HVAC (Heating Ventilation Air Conditioning) equipment.

What contaminants are in the air in my home

What Type of Air Filter do I Currently have In My Home?

The MERV (Minimum Efficiency Reporting Value)  rating system was designed to help tell how well an air filter removes particles from the air. What is MERV rating of the filter in your home? You may not even know because, more often than not, the company that services your HVAC system replaces the air filters during the service call. Each air return has a  grill that open so that you can replace your air filter. Depending on the size of your home you may have one air return to several. When replacing filters I see a lot of contractors use a cheap flat panel air filters with no MERV rating or a very low MERV rating.  I have asked contractor many times when they put that filter in over  the years and the answer is always the same. "This is the kind of air filter and I use is my self, those expensive air filters are a waste of money". Most people do not know much about how their HVAC system works so they just rely on what their contractor says. Basically all these cheap air filters do is  protect your HVAC equipment from large dust and lint. Essentially the cheap air filters with no MERV ratings can be so porous that particles that can damage your HVAC equipment, can pass right through the filter. Good air filters can protect the air quality in your home and do not have to be expensive.

Changing Your Lennox Filter: Note the size printed on the filter frame

Find Your Lennox Filter by Size or Model Number

How do I know what size filter to buy for my furnace?

  1. Check Your Current Filter Actual Size. Filters are labeled by nominal Size which is a round number. The actual size is the true measured dimensions of the filter by Length, Width and Depth. LxWxD for instance a 16x20x1 filter may have a nominal size of 16x20x1 but an actual size of 15.5x19.5x.75. Actual sizes of filters can vary by manufacturer. Some filters may include the actual size on the filter, otherwise you can simply measure to find the actual size of the filter.
  2. Check for Filter Model Number. Whole House filters are usually a filter that is about 3 to 6 inches thick. The best way to find a compatible replacement is to find a filter that is compatible with your current filters model number. Lennox filters for instance list compatible filter model numbers for Honeywell, Trion Air Bear and Carrier on the side of their filter.
  3. Manually Measure your current filters LxWxD(LengthxWidthxDepth) to get the actual size.

Where is the filter on my Lennox furnace?

  1. Check for the Filter Compartment before the Furnace equipment. Lennox Filters usually have the model number on the side of the filter. Lennox furnaces may have a compartment by the blower for a 1 inch filter or 1 inch vent filters in the return vents.
  2. Check for Filter Cabinet: If your system has a Lennox wholehouse filter you will probably have a filter cabinet containing the filter next to the air handler.

What is a MERV 16 filter?

A MERV 16 filter is a highly efficient filter capturing more than 95% of particles in the range from 0.03 to 10 micrometers which each pass through the filter. Lennox make residential MERV 16 filters that can work with Lennox systems and be used as upgrades to specific Carrier, Trion AirBear, and Honeywell systems. MERV(Minimum Efficiency Reporting Value) is a rating system create by ASHRAE(American Society of Heating, Refrigerating and Air-Conditioning Engineers) to measure the efficiency of air filters. MERV 8 is about the Level that begins to protect the air in your home. The higher the MERV rating the more efficiently smaller particles are filtered out of the air with greater efficiency.

How do I know what HVAC filter I need?

  1. Check Actual Size: Air filters are labeled with the Nominal Size(varies by Manufacturer and Model) which can be a rounded number. For instance a Lennox X6670 filter has a Nominal Size of 16" X 25" X 5" but an Actual Size 15-3/4" X 24-3/4" X 4-3/8". A 16x25x5 from Lennox may not be compatible with a 16x25x5 model from another manufacturer because they may have a different actual size.
  2. Measure Actual Size of your current filter. Use a measuring tape and find the LxWxD(Length, Width and Depth of your current filter)
  3. Check compatibility by Model Number. Filters may have a list of Models from Various Manufacturers which are compatible with the filter you need. Beware many filters models number are very similar, double check the actual size(true measured dimensions of the filter) to make sure you have the right filter.
  4. Find the Right Filter Rating: MERV(Minimum Efficiency Reporting Value) is a rating system for air filters create by ASHRAE(American Society of Heating, Refrigerating and Air-Conditioning Engineers) to measure the efficiency of air filters. Some companies use their own rating system such as Home Depot uses FPR(FILTER PERFORMANCE RATING) and 3M uses MPR(MICRO-PARTICLE PERFORMANCE).
  5. MERV 8(comparable to MPR 600 and FPR 5) is a good level to begin to protect air quality in your home. MERV 11( Comparable MPR 1000-1200 FPR 7)and MERV 13(Comparable MPR 1500-1900 FPR 10) are used in superior commercial buildings and in homes with allergy sufferer.
