How to Get The Right Filter Size Lennox Furnace Filter
When it comes to filters both size and compatibility matter. It is however important when looking for a compatible filter to understand filter sizing to make sure it is compatible with the exact model. First, you need to consider the actual size of the filter and make sure its actual dimensions match the filter you are replacing. Air filters are generally listed by their nominal size which can cause some confusion with consumers. What you might not realize is that filters are not sold by their actual dimensions. Instead, a rounded up number is used to label filter packages. This measurement is referred to as the "Nominal Size".

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 sometimes 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 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 opens 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.
