Air purifiers can remove dust and allergens from the home, as long as they are well maintained-the key here is to ensure that the filter is working properly. We will help you keep them in good working condition with tips to replace the filters when necessary.

The life of the filter depends on its type and the quality of the air it purifies. In order to extend the service life of the filter, please look for an air purifier with a pre-filter. This element can even capture larger particles before they reach your filter, but they may require more regular cleaning.

You should replace the glass fiber filter once a month. They are a low-cost option, but you need to replace them regularly. Pleated polyester filters have a lifespan similar to fiberglass, but are a bit more expensive than fiberglass-although they are better at catching particles. The HEPA filter can be used for about six months, and some people like to replace it every one to three months. The activated carbon filter can be used for three to six months. The electrostatic air filter can be used for several years. Again, these estimates will vary depending on the air purifier model and the conditions of your home.

There will be some signs that can help you determine exactly when the air purifier filter needs to be replaced.

A change in color does not necessarily indicate that it needs to be replaced. HEPA filters may look dark after a period of use, but they still work normally. As long as you have continuous airflow, the filter will work. In other words, reduced airflow and increased electricity bills may indicate that your purifier is working hard and is clogged by a clogged filter. If you want to get real technology about monitoring, you can use an anemometer to regularly check the airflow of the purifier.

If you see dust and particles around the vents of the air purifier, the filter is overwhelmed. These phenomena will be particularly noticeable if you put a piece of white paper on the purifier and let it run for an hour.

The main challenge of filter clogging is slow airflow. As particulate matter accumulates, it becomes more difficult for air to pass through, which can lead to increased use of purifiers and electricity. This can also put pressure on the machine, depending on the severity of the filter that needs to be replaced.

Some air purifier filters can only be cleaned and reused; it is assumed that the filter cannot be cleaned unless it is clearly stated on the label that it can be cleaned. Flushing a non-washable filter can damage it, so at most use a vacuum cleaner to remove residues on the filter you are not sure about. Remember that HEPA filters (the most common filter in air purifiers) can capture particles throughout the fabric, not just the surface. Simply wiping the top layer will not remove everything captured by the filter. In the worst case, doing so will remove the captured particles and discharge them into the airstream.

If you can choose, the washable filter is an environmentally friendly option, and you don’t need to throw away the old filter. Before placing the filter under running water, make sure that the manufacturer guarantees its cleanability.

Yes, air purifiers require replacement of filters; how long it takes to replace them depends on usage, size and environment. Carbon filters tend to have the longest service life, followed by HEPA filters.

Smart air purifiers can be a good supplement to any home. In addition to replacing filters, there are more things to make the most of them.
