Air filters in your home should be replaced and cleaned monthly, and they should be replaced more frequently if you live in an area with a high pollution level. If you spend a lot of time outdoors or engage in a dusty hobby, you should consider cleaning your filters every two weeks. If you use an air filter cleaner, here are some tips to clean it properly. If you notice a buildup of dirt or dust in your filter, it may be time for a professional cleaning.
Mechanical and electrostatic filters
In a residential setting, electrostatic filters work well for removing certain particles in the air. Because they are electrostatically charged, these particles will stick to them and be attached to the filter media. The media itself acts like stocking feet on a carpet, trapping the particles and preventing them from getting back into your home. The resulting clean air will not have the dust particles, pollen, or odors that are harmful to your health.
You can clean an electrostatic air filter by running water through it a few times a year. Unlike mechanical filters, water pressure will not be strong enough to remove particles. Instead, you should use a cleaning solution made specifically for electrostatic air filters. Once you have cleaned it thoroughly, rinse it with clean water, which will remove any dirt or debris that might have accumulated on the filter. This step is crucial to cleaning an electrostatic air filter.
While mechanical and electrostatic air filters are similar, the difference between the two is that the former is designed to capture airborne particles as small as 0.3 microns. This is based on research conducted in the 1950s and is often used in hospitals. While they don’t remove the same amount of particles as electrostatic filters, the efficiency of the air filter is generally higher than electrostatic ones. Electrostatic air filters, on the other hand, can lose their efficiency after several years of use and can become MERV 11 or MERV 8 as they age.
Electronic air cleaners
You can find electronic air cleaners in the form of separate filters, furnace parts, or both. They use an electronic charge to purify air before it enters the space. These devices are typically installed as part of the furnace system, or in individual housings. The electronic devices require a power source, as well as an external switch, and work by collecting airborne particles with a negative charge and attracting them to positive-charged collector plates.
Electronic air cleaners require little maintenance to function and require only routine cleaning or replacement. Some models use disposable filters that need to be replaced every six months, while others use collector cells that are hand-washable or can be placed in the dishwasher. However, it is important to clean your electronic air cleaners properly, and not over-clean them. Ensure they are dry and clean to maximize their air cleaning benefits.
Electronic air cleaners have the advantage of stopping particles, but they can also produce ozone. According to a study by the U.S. Department of Commerce, these devices can increase the levels of ozone by as much as six inside a home. Not only is ozone bad for the environment, but it can also harm people’s health, especially if it is exposed for prolonged periods.
Reusable air filters
You can clean reusable HVAC filters yourself with simple cleaning solutions. Simply hold your filter up to bright light, and if the light does not shine through, the filter needs to be cleaned. However, you should not assume that all filters are clean. Some reusable filters can be cleaned, while others will not. If you’re unsure whether your filter needs cleaning, check the manufacturer’s instructions to determine the proper cleaning method.
To clean a reusable HVAC filter, first, you should remove it from its unit. To do this, use a hose with a detachable nozzle. Then, fill the hose with clean water. While using the hose, aim the spray at the opposite side of the filter. This will wash the debris into the interior of the filter. Next, add some dishwashing liquid or mild household spray cleaner to the water. Repeat this process for both sides of the filter. Make sure the filter is completely dry before re-installing it in the system.
If you are using an electrostatic air filter, you can use a mixture of water and dishwashing soap to clean the reusable air filter. After a few minutes, rinse the filter with water to remove any hardened debris. Finally, prop up the filter so that the drain holes face down and let it drain for 15-30 minutes. You should then install the air filter in the proper direction so that the airflow arrow points in the right direction.
