If you have a HEPA filter in your vacuum cleaner or air purifier, it's important to know How to change hepa filter?. It's a small part of your appliance, but it's a big deal because it filters out particulates and dust from your home's air.
These tiny particles are the main reason why it's important to have a quality HEPA filter in your home or workplace. That's because these 0.3 micron particles can go deep into your lungs and cause respiratory problems for anyone who's allergic to them.
Remove the Cover
A HEPA filter has to be changed on a regular basis. Otherwise, it can become dirty and reduce its effectiveness. In turn, your air quality can suffer, which can lead to serious health issues such as allergies or rashes.
The cover of a hepa filter can be removed easily by using a screwdriver and removing the screws (x10) that attach it to the HEPA filter assembly. This will allow you to lift the filter out of the unit, taking care not to bump into or damage other components. Once the old filters are removed, you can install new ones. Make sure you read your product manual before attempting to clean any HEPA filters! Some are washable, while others must be rinsed out. If you’re unsure which type of filter your appliance uses, check the online product manual for instructions.
Unplug the Unit
One of the first things you want to do is unplug the unit from the power source. This is a smart move for many reasons, including saving energy. Most importantly, it is the safest way to remove the old filter. This also helps prevent any electrical damage to the unit, and keeps it running for longer.
The best part about this little trick is that it is actually very easy to do. Simply turn the machine off, and unplug the power cable from both the wall socket and the power supply unit, or PSU for short. Then, take note of the mounting screws. You will need to find and unscrew these in order to remove the PSU from the computer case. Make sure you do it correctly to avoid any future problems.
Remove the Old Filter
If your HEPA filter is starting to look dirty, it's time for a replacement. While you may be tempted to simply clean it, air purifier experts say that's not the best way to do it.
To replace the old filter, first move the bottom clips on your return vent cover to the open position. Next, lift the filter outward.
You should see an arrow on the old filter frame that indicates the correct airflow direction for the new one, says Mike Negron, CEO of the National Air Filter Association.
Remove the new filter from its packaging and install it in your unit, ensuring that it's installed with the arrow directed towards the furnace fan unit (and not into the room). You should also make sure to follow the filter manufacturer's recommended changing interval, which is generally 6 months.
Install the New Filter
HEPA filters are among the most important parts of any air purifier. They’re designed to trap the smallest particles in indoor air that can cause respiratory issues, including allergies and asthma.
However, even a HEPA filter can’t remove every particle from the air. To protect against pollutants that aren’t 0.3 microns, such as COVID-19 (a type of cancer-causing particle found in industrial gases) or volatile organic compounds (VOCs), experts recommend using an air purifier that includes other types of filters, such as carbon and pre-filters.
In addition, it’s a good idea to replace your filter at least as often as the manufacturer recommends. That way, you’ll be able to avoid having it become moldy or clogged with dust and debris.
Replace the Cover
Replacing the cover from your hepa filter is easy and can help you maintain clean air in your home. Dirty filters can cause health problems such as respiratory issues, allergies, rashes and skin conditions.
To replace the cover, turn the four locks on the unit per their directions and remove the front cover from the device. After the front cover is removed, replace the pre-filter and HEPA filter in their respective compartments, turning the 4 locks on each side to secure them.
The carbon filter should be installed first, with the foam face facing you, and the HEPA filter next with the seal facing you. The swivel tabs on the top of each filter should be aligned with the arrows on the housing. Reinstall the HEPA filter cover by using a Torx T20 screwdriver to reattach the screws (x10) that attach it to the filter assembly, taking care not to bump into other components.
