Air purifiers are helpful devices that circulate clean air by removing airborne dust, allergens, smoke, and odor. When used correctly, it will improve indoor air quality and help you achieve a happier, healthier lifestyle.

To prevent that from happening, here are some tips and tricks to help you get the best out of a working air purifier.
Short answer
Run, maintain, repeat.


1. Choose A Location That Does Not Impede Air Circulation

Having the best location for an air purifier is important. The closer it is to the pollution sources, the quicker it will capture harmful particles in the air. Avoid placing the air purifier at the corner of a wall. Leave at least 2-4 feet of space for unobstructed airflow circulation. Ensure there are no objects like clothes blocking the air inlet and outlet. For more comprehensive coverage, you can place an air purifier at the center of the room but take note of the risk of tripping over the wire.

Only place the air purifier on a flat surface like the floor or table to prevent it from tipping over. Avoid placing it next to electronic devices or underneath a window that may cause damage to an air purifier. The same goes with a wet area like a bathroom where the excess humidity will shorten the filter life.

2. Leave It On 24×7

An air purifier is designed to run 24 hours a day, 7 days a week of air purification. There is no need to turn it off even when you’re away. Leaving an air purifier run continuously prevents airborne particulates from building up and takes a long time to clean. Don’t worry too much about energy wastage as modern air purifiers are energy-efficient and Energy Star Rated. With auto mode, the air purifier would self-regulate only to use higher fan speed when a high concentration level of air pollutants is detected. If the particular model does not come with auto mode, leave it on at the lowest fan speed, and the air purifier can run efficiently with no high utility bill to incur.

3. Keep Windows And Doors Closed

To use an air purifier effectively, you must make sure all windows and doors are shut tight. Also, seal any leakage or gaps on drafty windows with a sealing strip. This is to prevent purified clean air from escaping and outside airborne pollutants from coming in. Otherwise, healthy indoor air can never achieve as the air purifier will have to run indefinitely to clean the air.

4. Change/ Maintain The filters Regularly

Air purifier filters require scheduled cleaning or replacing to prevent clogged with contaminants. For permanent/ washable pre-filter, use a vacuum cleaner attached with a soft brush head, gently vacuum it without applying pressure to the mesh. For hard stains to remove, you can use lukewarm water and gently rinse it off. Leave it air dry for a couple of hours before installing back the filter. We recommend cleaning the pre-filter every 2 weeks or when there is a dip in the performance.

For other non-cleanable filters like HEPA and carbon filters, replace them according to the interval time or when the filter change indicator light is lit. After replacing the filter, remember to reset the filter indicator. Do not attempt to clean the filter as it may permanently damage the dense fibrous materials. Above all else, read and follow the manufacturer’s instructional manual on maintaining the air purifier.

5. Clean The Air Purifier’s Sensor

Air purifiers with built-in air quality sensors need to be cleaned periodically. The sensor monitor and send accurate data to the device for autonomous features. You can easily clean the sensor lens dust with a cotton swab or microfiber cloth. Do this monthly or when the air purifier inaccurately/ fails to detect the rises of nearby pollutants in the air.

6. Choose The Right Size Or Use Multiple Air Purifiers

Knowing your room size is vital in deciding what size of air purifier to go for. Choose the ideal size air purifier with the capacity to cover an entire room or leverage with multiple small air purifiers. You can find out if an air purifier can support a particular room size by looking at its Clean Air Delivery Rate (CADR). Better yet, use the manufacturer’s recommended room size square footage as a benchmark.

The Do’s And Don’ts

When an air purifier is used the right way, it can make a big difference in your home's air quality. Here are more tips on how you should and should not use an air purifier.

  • Do not use air purifiers outdoor. We cannot emphasize this enough.
  • Turn off and disconnect the plug from the electric outlet before attempting cleaning or moving the air purifier.
  • Supervise children that they do not go near the device. Some air purifier comes with a child lock feature that can be activated to prevent children from fiddling with the control settings.
  • Avoid storing or spraying insecticides, fragrances, flammable items near the air purifier. The toxic substances could damage the unit or cause an explosion.
  • Only use an air purifier with its local power voltage. Due to fire risk, do not alter the voltage output with a boost converter or transformer.
  • An air purifier should not be used without all the filters installed properly.
  • Stop using an air purifier immediately when smoke comes out of the machine. Send it to the nearest authorized service center for repair.

In conclusion, air purifiers remove airborne impurities and help improve your quality of life. Depending on your needs, consider getting a medical-grade air purifier that offers the best filtration against ultrafine particles.
