We are pleased to inform you that ALS Cooling and Heating is one of less than 30 contractors participating in a Residential Maintenance program. Stop breathing dirt, dust, dust mites debris, lint, odors, mold spores, pollen, dander, aerosols and cleaners! $100 Rebated Advanced Tune-Up Given that Dust mites and most all pollen is over 10 micron in size, these filters will remove 70% or more of these airborne contaminants! We have filters to fit most sizes, call today. The Merv 8 is over 70% efficient at the 3 to 10 micron range! The EPA has published on their website that a MERV 8 rating is nearly as effective as a true HEPA filter in most residential applications. Our filter with a MERV Rating of 8! THREE times that of the basic filter. Choosing a filter with too much restriction to airflow will cause your furnace to work harder and could increase your energy bills and lead to increased equipment failure.Best AC Filter for Air Conditioning Conditioning Filter For Air Flow? Air Filters: MERV Rating Of 8 Generally filters with a higher MERV rating have a more profound effect on airflow. Using an HVAC filter ranging between a 9-12 MERV rating is an excellent means of controlling dust and other particles.Īnother important aspect to consider when choosing a filter is airflow restriction or static pressure drop across the filter. There are also UV filters, which are high-end filters that contain all the components of a traditional but with a germ killing UV light. Some are made from 4-5” pleated synthetic cotton attached to a rigid metal grid, these filters can trap up to 95% of particles down to 0.3 microns in size including very tiny dust particles, pollen, mold and other irritants. High-efficiency air filters are generally considered the most effective filters for most residential HVAC systems. MERV Rating: 6-13 High-efficiency air filters Pleated air filters can be purchased for around $15 each or less, and like electrostatic air filters, only need to be switched out every three months. Made from polyester or cotton paper, – the more pleats, the greater the coverage. It is recommended to replace disposable electrostatic filters every three months to keep your home free of airborne allergens.Ī step up from and better investment than fiberglass air filters and more popular than electrostatic air filters, disposable pleated filters capture between 70-90% of the airborne pollutants in your home between 3 and 10 microns. These filters are good for homes with children, pets or smokers, and are affordable in standard sizes. The electrostatic charge is created by air flowing through a maze of the static-prone fibers. MERV Rating: 1-4 Electrostatic air filtersĭisposable electrostatic air filters contain self-charging electrostatic cotton or paper fibers that attract and trap small particles. It’s recommended to replace them once every month. Originally designed to protect heating and air conditioning equipment, these filters are less effective when it comes to improving indoor air quality. Often available for less than $10, fiberglass air filters have thin flat surfaces that trap particles and clean the air but only catch up to 20% of pollutants ranging from 3 to 10 microns, removing mainly larger particles like dust, lint and small insects. Listed below are some of the most common types of residential HVAC air filters, and the MERV rating you can expect to find on each one: Fiberglass air filters Filters with a MERV between 7 and 12 are considered good quality.Īlthough filters with a higher micron/MERV rating cannot eliminate the need for dusting, they can help reduce the need. Air filters with lower MERV ratings will remove a smaller percentage of pollutants from your home. Generally speaking, the cheaper the filter is, the lower the MERV number is. For residential purposes, MERV ratings range from 1-16. Being able to choose the best air filter takes a basic understanding of MERV ratings (Minimum Efficiency Reporting Value), and how they reflect the quality of the filter.Īn air filter’s MERV indicates its ability to capture airborne particles while air is flowing through your heating or cooling system. Selecting the right air filter for your home can be a confusing process, with so many products available in the market. Unfortunately, filters have a short lifespan because they fill up quickly with all the pollutants, dust particles and allergens in the air. That’s because dirt can cause furnace or air conditioner failure and an AC or furnace filter’s main job is to stop dirt and dust from entering your equipment. It also means you can breathe easier knowing that your heating and cooling system isn’t being overworked and raising your utility bills. Removing pollutants from the air in your home means you and your family can breathe cleaner.
