These days it does not seem to matter what you are going to the store for there are tons of options for you to select from once you get to the store. Think of the last time you want to go get milk. You can choose from soy milk, almond milk, powdered milk, organic milk, whole milk, fat free milk, 1% milk, and 2% milk. How do you decide which one to purchase? You may also have the same overwhelming feeling when you go to pick out your next air filter for your air conditioning unit. Today we are going to talk about the electrostatic air filter so that you can see if it is the right fit for your home.
What Do Air Filters Do in a House?
First let’s talk about what the purpose of an air filter is. An air filter’s function is to clean the air that circulates through your heating and cooling system. As air passes through the filter it traps different particles that could affect the health and comfort of those in your home. Filters will trap dust; dirt; pollen; mold and mold spores; fibers and lint; metal, plaster, or wood particles; hair and animal fur; and bacteria and microorganisms.
MERV Filter for Furnace Filters
Another thing you will need to understand is how the efficiency of an air filter is measured. All air filters are given an efficiency rating called a MERV rating. MERV stands for minimum efficiency reporting value. An air filter is given a MERV rating from 1 to 16. The higher the MERV rating the more efficient the air filter will be.
For many years the only type of air filter available were disposable air filters. Disposable air filters are inexpensive to purchase. While they do filter out some particles and contaminants they have a low MERV rating. Over the years more effective air filters have been invented and introduced to consumers.
How Does an Electrostatic Air Filter Work?
One type of air filter that has been introduced is the electrostatic air filter. Electrostatic air filters have multiple layers of vented metal for air to pass through. The electrostatic air filter is able to use the static electricity that is created as the air passes through the layers of the filter to help trap more particles than other filters. As air molecules pass through the first layer of the filter they are positively charged by friction that is caused between the air and the filter. The positively charged molecules then attach themselves to the next few layers of the filter as the air passes through.
Washable Electrostatic Air Filters
Another one of the perks of an electrostatic air filter is that they are washable. Instead of replacing your air filter every month you simply take it out and use your garden hose to wash the filters off. Not having to replace your air filter will definitely help you save money. If you are buying cheaper filters you may not feel the savings too much but if you are purchasing more quality air filters with a higher cost you will definitely appreciate not having to make that purchase each month.
