Changing an Air Purifier Filter
If your air purifier has a pre-filter, more than likely it will need to be changed monthly, while the actual filter may only need to be changed twice a year. Many air purifier companies offer filter renewal subscriptions that can save you money over time.
Depending on the size of your air purifier and design, access to the filter may be a small door on the back, on the bottom, or even on the side. If your unit has more than one filter, be sure to take note of the proper locations for each filter. Generally, a pre-filter goes around or outside of the main filter.
Here are some examples of how to change a filter on an air purifier from 3 popular brands.
The Pure Company Large Room Air Purifier
To change the filters, unplug and turn off the air purifier, then unlock the bottom by sliding the latch to the right and finally lift the unit off its base. To replace the Carbon Pre-Filter, simply remove the old one and wrap the new Pre-Filter around the True HEPA Filter. Make sure the Velcro is secured.
To replace the True HEPA Filter, remove the new filter from the plastic bag and repeat the steps for the Carbon Pre-Filter before placing the True HEPA Filter in the designated spot in the Large Room Air Purifier. Place the air purifier back on the base and lock it into place by sliding the latch to the left. Hold down the filter indicator light for 3-5 second to reset it.
QuitePure Home Air Purifier
This HEPA air purifier uses one filter that needs to be replaced every 6-12 months or as needed. The Replacement Combo HEPA Filter Cartridge removes dust, pet dander, odors, allergens, viruses, and bacteria from your indoor air.
To replace the filter, turn off the unit and unplug it. Turn the unit upside down and twist off the large cap on the bottom. Pull out the old filter and discard. Remove the new filter from its packaging and insert into the QuietPure Home. Place the cap on the bottom and twist to secure in place. Turn the unit back over and you can begin operating it again.
Blueair Classic 205
The Blueair Classic 205 air purifier uses a HEPASilent Particle Filter to remove allergens, pet dander, pollen, mold spores, viruses, bacteria, and dust from your indoor air. The filter should be changed every 6 months.
To replace your filter, unplug the unit and open the back door of the air purifier and remove the old filter. Insert the new filter and close the back door. Hold down the filter reset button for 10 seconds, then your air purifier is ready for use.
Always check with your user manual before changing a filter. Make sure to buy the right filter that goes with your unit to get the correct fit. Filters are unique to the air purifiers they’re designed for. Proper maintenance is necessary to keep your air purifier running smoothly and increasing its lifespan.
