If you're not sure what to buy, look at the size you already have after you pull it out. Basic air filters take care of things like dust and dirt. You can also buy filters to help reduce allergies, as they filter out more particles. However, the more they filter out, the less efficient they are because AC has to work harder to get the air through the filter. Look for the return air duct. Usually, the return air is located near your thermostat, either on the same wall or nearby.
Department of Energy Official site for the U. Department of Energy, which provides resources related to energy safety, conservation, and efficiency Go to source. Pull open the return cover. Find the fasteners to pull open your grill work. Often, you'll have little fasteners that pull out and allow you to open one side of the cover. Lean the cover out towards you.
Remove the old filter. Take the old filter out, being careful of the dust. Click here for individual plan details. Ready to schedule furnace repair service or a furnace tune-up with Jerry Kelly in St.

Your air conditioner depends on a series of filters in order to properly cleanse the incoming air from dust, dander, and other irritants which get caught inside your cooling system.

Directing the airflow so that it does not blow directly from one person to another reduces the potential spread of droplets that may contain infectious viruses.
Air cleaning may be useful when used along with source control and ventilation, but it is not a substitute for either method. Source control involves removing or decreasing pollutants such as smoke, formaldehyde, or particles with viruses. The use of air cleaners alone cannot ensure adequate air quality, particularly where significant pollutant sources are present and ventilation is insufficient.
Some products sold as air cleaners intentionally generate ozone. These products are not safe to use when people are present because ozone can irritate the airways. Do not use ozone generators in occupied spaces. When used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants.
Bipolar ionization also called needlepoint bipolar ionization is a technology that can be used in HVAC systems or portable air cleaners to generate positively and negatively charged particles. Provided manufacturers have data to demonstrate efficacy, manufacturers of these types of devices may market this technology to help remove viruses, including SARSCoV, the virus that causes COVID, from the air, or to facilitate surface disinfection of surfaces within a treated area.
This is an emerging technology, and little research is available that evaluates it outside of lab conditions. As typical of newer technologies, the evidence for safety and effectiveness is less documented than for more established ones, such as filtration.
