The Benefits of Air Filters: What You Need to Know

Air filters are an essential part of keeping your home clean and healthy. Not only do they remove dust, allergens, mold spores, and other pollutants from the air your family breathes, but they also filter out fine dirt particles that can degrade the performance of the HVAC system itself. When looking for the right air filter for your home, it's important to consider the thickness of the filter. A 1-inch filter will clog with particulate matter much faster than a 4- or 5-inch filter.

Additionally, check the manufacturer's recommended replacement dates on the packaging to get an idea of the value of a thicker air filter. No, HVAC air filters differ in quality and dimensions, and some have features that others don't. In most cases, it's best to use the filter that your HVAC manufacturer recommends matching with your system. If you have significant problems with dust, pet, or mold allergies, a UV air purifier can make a dramatic difference. It's also important to note that some days are worse than others for air pollutants, and the government will occasionally issue warnings for the elderly, the sick, or young children.

Air filters are especially important for people who live in a highly polluted area because they can filter out harmful contaminants from the air. In addition to the obvious steps, such as keeping windows and doors closed, turning off bathroom fans and range hoods can also help reduce air pollution. An electrostatic air filter is a washable air filter that uses static electricity to capture particles. In addition, an oft-cited comprehensive independent test of the effects of MERV filters 8 to 13 on HVAC airflow and energy consumption concluded that even “if no adjustments are made for the increased pressure drop of high MERV filters, airflow and Energy penalties are unlikely to be serious at least, not until the filter is loaded with dirt.”You've probably heard how important it is to change your home's air filter on a regular basis. By removing air pollutants (both chemical and environmental), your family will be able to breathe cleaner air every day and your electricity bills will also be lower because your HVAC unit won't have to work as hard.

Regularly replacing your air filter is the best thing you can do to keep your HVAC system running. The cheapest disposable fiberglass filters only meet the minimum (or slightly better), around MERV 2 or 3, and are designed to protect the inner workings of your HVAC system, rather than indoor air quality. These are installed on wall-mounted return air grilles (more common in the South) or on the air handler (more common in the Mid-Atlantic and North Atlantic states).The experts at David Gray Heating & Air have extensive experience and knowledge to help you with your air filtering needs. They can provide advice on which type of filter is best for your home and how often you should replace it. With their help, you can ensure that your family is breathing clean air every day.
