And even if you do, you might not know it needs to be replaced every few months to keep your furnace running at peak efficiency—and to help prevent pollutants from entering your living space.

Fortunately, replacing a furnace filter is a pretty simple task, once you know what you’re doing. There are ways to botch the job, however, for example by buying the wrong furnace filter or putting it in backwards, which could block the flow of air instead of cleaning it. Here’s how to do the job properly in three simple steps. What kind of filter do you have? Start by turning off the furnace. Remove the existing furnace filter, which will be located inside the furnace or inside the return air vent. water noise in window ac unitLook for an arrow on the filter indicating airflow direction. best central air conditioning unit 2013Using a permanent marker, draw the airflow direction on the outside of the furnace, so you'll always know the right way to install the filter. air handling unit power consumption

Then note the furnace filter size, which will be printed on the cardboard frame.A filter that has a plastic frame is a reusable model. That means you have clean it only periodically with a vacuum and water, ideally outdoors. Let it dry completely before reinserting. Get the right replacement. Furnace filters are sold at home centers, hardware stores, and online. Disposable ones are typically 1 or 2 inches thick. Check our Ratings of furnace filters, also known as whole-house air filters, for a right-sized model that was effective at removing dust, pollen, and smoke when air passed through it at both high and low speeds. We also test thicker furnace filters, some up to 5 inches, and they often provide superior air cleaning. But if your furnace isn’t already equipped to handle a thicker filter, it will need to be modified by an HVAC professional. Our top-rated 5-inch furnace filter is the Lennox Healthy Climate CarbonClean 16, $100. For 1-inch furnace filters, we recommend the Filtrete Healthy Living Ultimate Allergen Reduction 1900 MPR, $20.

Then slide the filter back into place and replace any cover that goes over it. Keep a record of the date so that you’ll know when it’s time to change the furnace filter again.

As you shop, choose an air filter that targets the pollutants present in your home. If you are living in an environment that is commonly subject to odor from a litter box, cooking fumes, aerosols or pesticides, a carbon air filter works best. For allergies, look for allergen filters that specifically target dust, pollen and mold.

Air filter sizes vary depending on your heating, ventilation and air conditioning (HVAC) system. If you are unsure of the specific size needed, consult your HVAC system's owner's manual for proper specification. Keep in mind that the best air filters for your HVAC system need to fit tightly. A filter that is too loose may let additional pathogens flow around it and into your home.When it comes to air quality, Walmart's got you covered.

As a general rule, electrostatic air filters cannot even come close to the filtration power of a high quality anti-allergen filter from 3M or Honeywell, but that doesn’t mean you should rule them out altogether.  In this article, we will discuss what an electrostatic air filter is, how it works, the pros and cons of using one and whether or not washable furnace filters would work for your home. Electrostatic air filters are washable air filters that theoretically never need to be replaced.  I say ‘theoretically’ because I have a hard time believing that something that is subjected to dirt and debris regularly will work indefinitely, but that is the standard claim.  The idea is that instead of replacing your electrostatic air filter at regular intervals like you would a conventional air filter, you take them out back and wash them off with a hose about once a month.  This is a handy trick if you are sick of spending money on conventional air filters, but do electrostatic air filters work?  

They do work, but the question is do they work as well as a conventional air filter? For more information on conventional air filters and how often you should change them, take a look at: Air Conditioning Filter Change – How Often Should I Do It? These washable furnace filters work by having multiple layers of vented metal which the air passes through.  As the air passes through the first layer of filtration, the air molecules are positively charged by the friction between the air and the filter.  The now positively charged air molecules attach themselves to the next few layers as they pass through the rest of the filter.  Think about it as working kind of like walking across the carpet with your socks on and then touching a door knob – the process of walking across the carpet charges you with static electricity which is then released when you touch a grounded surface like a door knob.  Only instead of your socks scooting across a carpet, it is the air scooting across your air filter that creates a charge and traps dust particles in the air filter.

One of the most attractive parts of washable air filters is the fact that you never have to buy a new one.  This is definitely a plus, I mean who wants to buy a new air filter every few months?  Even if you opt for the cheaper air filters that run you 50 cents each (which I do not recommend), you still have to go through the hassle of buying them and replacing them on a regular basis and who wants to deal with that? The other appealing part about using electrostatic air filters is the price.  If you are buying high quality air filters then you may be spending $15 every few months which adds up to around $60 each and every year.  Now even though this might not break the bank, it can add up over time.  Washable furnace filters cost around $50 to $60 each but never have to be replaced, meaning that they pay for themselves in the first year of their use.  

You can’t argue with the cost of these filters, so it may be an option to keep in mind. I have to say that the cons of an electrostatic air filter far outweigh the pros, in my opinion.  There are several problems with a washable air filter, ranging from how effectively they filter your air to how often they have to be washed.  Some of these problems are a matter of preference, but some can’t be argued with and should be kept in mind before making your decision: Electrostatic air filters can only filter so much.  One of the problems with electrostatic filtration is that it relies on static electricity to operate.  What I mean by this is that static electricity is powerful enough to filter small, lighter dust particles out of the air but what about larger dust and dirt particles?  Unfortunately, this is one of the areas that electrostatic filtration falls short in.  An electrostatic air filter will never be able to filter as well as a high quality HEPA filter or even a moderate 1200 MPR filter (micro particle performance rating).  

These filters are designed to filter out everything down to a certain specification size and are good at what they do.  If you have someone in your house who suffers from asthma or bad allergies, then I’d definitely recommend you avoid washable furnace filters and instead opt for a high-filtration replaceable filter with at least a 1400 MPR.  For more information on this, take a look at: How to Reduce Asthma Symptoms and How Your Air Conditioner Can Help. Other problems with electrostatic air filters include: Just food for thought before investing in a washable air filter.  For information on how to prevent mold and whether or not you need to have your air ducts cleaned, take a look at these helpful articles: Should I Have My Air Ducts Cleaned? How Do You Prevent Mold? It depends on what you mean by ‘work.’  They do remove some dust particles from your air, but overall I do not recommend electrostatic air filters for home use.  Electrostatic air filters are an interesting technology but they just won’t work as well as a 3M 1600 MPR and they never will.
