Air Filter vs Air Purifier

You’ve probably wondered if there’s much difference between an air filter and air purifier. The quick and simple answer to this question is ‘YES’. Although they both work to alleviate contaminants inside your home, they do it in very different ways.

How Does an Air Filter Work?

Air filters for the home are part of your HVAC system. They allow air to re-circulate back through your home after filtering out impurities such as pet dander, dead skin, cigarette smoke, pollen, among others. The air filters help your HVAC system run at peak performance and extend the life of the HVAC unit by keeping dust and dirt from entering the ducts. Over time, the filter will become clogged with the debris that it removes from the air, loosing efficiency. This is why it’s so important to replace your air filter every 30 to 90 days, depending upon the filter type.

A clean air filter has a tremendous impact on the quality of air inside your home. Air filters for allergy season can help alleviate a number of uncomfortable symptoms, including runny, stuffy nose, sneezing and wheezing by catching allergens in the air.

What Does an Air Purifier Do?

A typical air purifier uses the same method for filtration to remove pollutants from the air such as cigarette smoke, pollen, dust, etc.  In this way, it removes the same sort of impurities that home air filters do, and some people use them to specifically remove odors.

There are several types of air purifiers and each work a bit differently. You just have to pick the better fit for your needs. For example, the activated carbon purifier is commonly used to remove odors from the air, but falls short when it comes to removing pollen, dust or other fine particles.

Myths about Air Filters: BUSTED!

Let’s face it, you’ve postponed purchasing replacement HVAC air filters because you haven’t really realized how important they are for air quality of your home. Your HVAC system works constantly to keep your family warm in winter and cool in summer while improving the quality of the air. Therefore, we have compiled this list to set the record straight of common myths that you have heard or seen circulating about air filters.

One

Air Filters Only Minimize Dust – FALSE! While a quality air filter will do a lot to minimize the dust in your home, there is so much more a filter can do! Many filters can reduce the impact of pet dander and help eliminate mildew, viruses and bacteria in your home. If you invest in air filters for allergy season, you can reduce the impact of common allergens the entire family.

Two

My Filters Don’t Need to Be Changed That Often – FALSE! The experts are correct on this one, you need to change your filter every month. If you typically buy air filters with higher MERV Ratings such as MERV 11 or 13, then it is recommended that your filter changes every THREE months. However, if you have respiratory ailments such as asthma or allergies, monthly air filter changes still apply. This rule is especially strict on smokers and those with indoor pets, regardless of MERV rating.

Three

I Can Run My Furnace Without a Filter – FALSE! Running your furnace without the filter is a huge no-no! Without a filter, dust, dirt and debris will be allowed to blow freely throughout the home. Furthermore, you don’t want an expensive HVAC bill because this can cause significant damage to your HVAC unit. This practice is quite hazardous and could be costly.

Four

All Filters Are the Same – FALSE! There are different styles and types of filters. The air filter you choose is based on the current conditions of your home. If someone in your home has severe allergies or asthma, it makes sense to choose a filter that is designed to catch allergens. Others have many variations such as odor reduction, fiberglass, deep pleats or washable.

Five

If the Filter Fits, It Works – FALSE! If you have an HVAC filter that is not a perfect fit, it will not work as well and can lead to problems with your unit. Various brands such as Honeywell and Carrier, works better with filters belonging to that brand or replacements. To ensure you purchase a replacement air filter that fits perfectly, annotate the measurements. If there are no measurements displayed on the filter, you may need to measure your filter.

Six

There is No Wrong Way to Install Air FiltersFALSE! Arrows are key for installing the air filter the correct way. When installing air filters for the home, check out the arrows that indicate the air flow on your filter and your unit. If there are no arrows on your unit, you may need to refer to your owner’s manual. Installing the filter, the right way will make a big difference in how well the filter operates.

Seven

Air Filters Don’t Help with Allergies or Asthma – FALSE! While an air filter may not be a miracle cure for asthma or severe allergies, a filter can improve symptoms-especially when utilized with other preventative measures. In an article by WebMD, the EPA and the American Lung Association both recommend the use of air filters to reduce allergy or asthma symptoms.

As you can see, there are quite a few myths floating around when it comes to HVAC air filters.

 


Do I Really Need to Change my Furnace Filter?

YES! Freezing temperatures can make your furnace work harder and without the proper maintenance it can cause the unit to break.

During peak winter months, one of the main causes of failure is a clogged filter. Whether a residential, commercial or industrial furnace, your HVAC system needs the filter changed with more frequency during peak seasons. This is an easy and inexpensive step but a very important one!

Furnace filters can be trusted with catching dust, pet dander, and other airborne bacteria, depending on the efficiency, but when your filter is old a few things happen: your filter gets clogged, your furnace has to work harder to push air through, and what does make it through are particles of the dust and build up. Checking and changing your furnace filter regularly help avoid all of these things.

A clean filter will not only help your furnace continue to operate efficiently but it will also extend its life, improve air quality and help you with allergies and asthma.
