Hence, you can expect long term and short term health benefits from investing in a high performance air purifier. Aside from helping you sleep better, keep your lungs healthier and neutralize foul odors, it also helps prevent airborne diseases.

some common questions on how to use an air purifier

#1. ‘Where Should I Place my Air Purifier?’ – Place it at the source of pollution, away from corners

Place your newly bought air purifier where its top side and four sides will not be obstructed with any walls or objects.

The reason for this is many air purifiers are designed with a front or side air intake, with the clean air dissipated at the top. If you obstruct the inlet or outlet by putting it near the wall, then it might have a hard time drawing dirty air from your environment.

If you have a small room, you can put it at least 10 to 15 cm away from the wall or any object.

Remember that air purifiers work by taking in dusty and polluted air, cleaning it and releasing it. So the best place to put an air purifier is to where the pollution is mostly coming from. For example, near your doorway or in the direction of your window. You can also place quiet air purifiers in your bedroom to help you better sleep at night.

#2. ‘Should I sleep with an air purifier on?’ – Yes, Always Keep it ON!

To save up energy, you can run it at lower speeds, especially if you’re not home. Leaving it on will prevent particulates, gases and viruses from circulating your place, even if you’re out at work.

Air purifiers nowadays are energy-efficient anyway, so it won’t create much of a stress when it comes to electric consumption.

There are also air purifiers which can run in auto-mode and can automatically run at a higher speed whenever it detects an increased amount of contaminants in the air. This will monitor your air quality for you and will automatically consume less power when the air is clean.

#4. ‘Can I Use an Air Purifier with Windows Open?’ – 30% More Filtration Efficiency at Closed Windows

Most air purifier manufacturers suggest it’s better to keep windows closed while running your machine. While this is exactly true, you can still get it to work significantly with windows open.

According to a study conducted by Smart Air Filters, you can reduce pollution levels up to 60% even if you have open windows. But a room with closed windows can even filter 90% contaminants. This makes about a 30% difference in the amount of contaminants filtered.

An air purifier is not designed to clean all the outdoor air similar to an air conditioning system. Hence, to get the most out of your air purifier, do not open your windows all the time.

#5. “How Often Should Filters be Changed?” – 12 Months Tops

A simple guide is as follows:

  • HEPA Filters: 12 to 18 months replacement
  • Activated Carbon Filters: 3 to 6 months replacement
  • Pre-Filters: Clean every 30 days and replace once worn out
  • Permanent Filters: Cleaned every after 3 months, replace it when damaged.

Manufacturers require filter replacements every 3 to 12 months to fully optimize the machine’s life and avoid circulating polluted air. Not that this is a way for them to earn more for every filter replacements each year, but this is actually backed up by studies.

Through tests and extrapolation, Smart Filters found out that a large room air purifier HEPA filter with 130 sq. meter coverage can generally last 22 months. On the other hand, a HEPA filter used in a room of 85 sq. meter can exhaust its lifetime in about 13 months.

Room Size

Lifespan

85 sq. meter

13 months (3,120 hours)
130 sq. meter

22 months (5,280 hours)

To use your air purifier optimally, make sure to read your manufacturer’s guidelines in filter maintenance and how often you should replace it.

If you neglect replacement schedules, this will result in bacteria and dusts recirculating your indoor air environment.

#6. ‘Can You Use a Fan With an Air Purifier?’ – Yes, To Boost Circulation

Although air purifiers do their best at reaching air in every part of your room, it may not be able to cover far areas. This can be areas with partitions, large furnitures and behind cabinets. In order for air to move around from these places into your air purifier, you can use an extra fan.

If you originally have a fan in your home, move it in areas far from the air purifier’s reach. It will blow and move the air around towards your purifier, making sure no dirty air is ‘left unturned’.

Bottom Line

To maximize the performance and use of your newly-bought air purifier, you need to follow certain precautions such as:

  • Choosing the best location to put it.
  • Always keeping it on, even if your asleep
  • Never turning it off when you’re not home
  • Keeping your windows and doors shut
  • Changing your filters regularly
  • Using a fan to boost circulation
