Is MERV 11 bad for your furnace?
Using an air filter with a MERV rating that’s too high is just as bad as using one that’s too low. In particular, using an air filter with a MERV rating that’s too high can damage the compressor, heat exchanger, and air conditioner coil. In most cases, a MERV 11 air filter isn’t too high for residential use.
What is the highest MERV rating for a furnace filter?
Well, MERV ratings range from 1 to 20, with 1 being the lowest level of filtration, and 20 being the highest. Filters that are MERV 16 through 20 are usually only found in hospitals, cleanrooms, and nuclear power plants. The home air filters you’re looking for are rated anywhere between MERV 5 and 13.
Are high MERV filters bad for HVAC?
Wrong. While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow. If the MERV rating on your furnace is too high, it may force your furnace to work too hard and leave it vulnerable to damages.
Why is my air filter blue?
The blue filter on the right is clean and new. If your air system is working properly, then your filter will look like the dirty, used one on the left. Routinely changing or cleaning the filters from your home’s heating and air conditioning system helps the units run more efficiently and enjoy a longer lifespan.
What is the best MERV rating for home use?
According to the ASHRAE, the best rating for residential HVAC systems is MERV 13. But before you upgrade your filter, make sure your specific system can accommodate that rating. A higher MERV rating often means lower airflow, which can cause the system to work harder—use more energy—to do its job.
What MERV rating do I need for Covid 19?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
How long do blue air filters last?
six months
Blueair recommends a filter change every six months. The light on your filter timer will indicate when it is time to replace your filter after six months of continual use. If you use your unit in a highly polluted environment, you need to change it more often.
How do you replace a furnace filter?
Slide the filter out of the furnace; replace filters that appear dirty or clogged. If your Carrier furnace has a washable filter, rinse the filter under cool running water until clean. Allow washable filters to air dry before reinstalling them in your furnace.
Should my furnace have an air filter?
While AC and furnace units do a decent job of filtering air impurities on their own, return vent filters can aid in this by acting as the first line of defense. Granted, regular air filters have their use but a secondary option could be the step you need to keep your HVAC system clean and efficient.
Do all furnaces have air filters?
Answer: That depends on what type of furnace you have. If you have a warm air furnace then you have an air filter. If you have a boiler and radiators then you probably don’t have air filters.
