When to Change the Filter on Your Air Purifier?

Learn when it's time to change your air purifier filter - from fiberglass to HEPA - so you can enjoy optimal performance and cleaner air.

When to Change the Filter on Your Air Purifier?

Most air purifier manufacturers recommend changing the filter every 3 to 6 months for optimal performance. For those with allergies, asthma, or who want cleaner air, it is recommended to change the filter every 30 to 60 days. Fiberglass filters should be replaced every month, as they are a low-cost option but require frequent changing. Pleated polyester filters last about the same time and are slightly more expensive than fiberglass, but they are better at trapping particles.

HEPA filters can last approximately six months, while some people like to replace them every one to three months. Activated carbon filters can last between three and six months, and electrostatic air filters can last for years. These estimates will vary depending on your air purifier model and your home conditions. For example, Sqair HEPA filters should be changed every 1400 hours, which is 6 months if you run the Sqair high for 8 hours a day.

The EPA states that studies show portable air purifiers (or air purifiers or disinfectants) can achieve small improvements in cardiovascular and respiratory health by reducing indoor pollutants. Some models indicate when it's time to wash, vacuum, or replace filters. In general, a HEPA filter needs to be changed every year, pre-filters last 30 days, and carbon filters can last three to six months. Clean the permanent filters every three months and replace them if they are damaged.

Advanced air purifiers such as the Coway Airmega will notify you when to clean or change any of your air filters. Carbon filters should be replaced approximately once every six months, and True HEPA filters approximately once a year, depending on the amount of air they have processed. When the pre-filter indicator light is on, clean the unit pre-filter to ensure that Airmega can operate at maximum efficiency. Vacuums vacuum and trap allergens, hair, dirt and more from floors and upholstery with built-in bags or filters that help contain fine particles, especially with HEPA models. Cleaning these filters is as easy as taking them out and cleaning them with a vacuum or a little warm water.

Washable filters are an environmentally friendly option that avoids the need to throw away old filters. If you have a water filter in your refrigerator for ice machines or water dispensers, change them every six months or as recommended by the manufacturer to remove contaminants such as lead, traces of pharmaceuticals, and microbial cysts. Although it depends on the specific filter you have, as a general rule HEPA filters should be replaced every 6-12 months depending on air quality and environmental factors. Failure to clean and replace the air filter on a regular basis is essentially a problem for the environment. Smart air purifiers can be a great addition to any home, and there's more to getting the most out of them than simply changing filters. Anyone with well water can have a whole-house filter that needs to be changed every 30 to 90 days to prevent contaminants and unwanted chemicals from entering the home. Now that you know how and when to replace filters, there's nothing stopping you from enjoying the full-capacity cleaning of your revised air purifier.

Therefore, I decided to contact the popular brand Medify Air to ask them based on their recommendations.
