How to choose a good air purifier for a small room?

Best Small Room Air Purifiers That Are Worth Your Money

Filtration

When it comes to choosing the filtration of an air purifier, HEPA filters are the most popular.

It stands for High-Efficiency Particulate Air filters, known as the most effective models nowadays. They are proved to remove up to 99,97% of airborne allergens in the air, including the tiniest size – 0.3 microns.

That means this type of filtration can filter pet dander, ragweed, mold spores, dust mites, dust, and pollen – something that the traditional models hardly do.

Determine your indoor air quality needs

I mean “Do you have any specific needs?” Such as:

  •         Chemical sensitivities
  •         Pet allergy sufferers
  •         Smoke removal
  •         Asthma
  •         Allergies

In these cases, find an air purifier that is designed specifically for such symptoms or health problems.

For instance, there are asthma air purifiers for asthma sufferers. These models are specifically added a chemical and odor filtration to prevent users from being triggered by such substances.

Otherwise, a HEPA air purifier is enough for general air quality improvement.

Size

The size of your air purifier depends on the square footage of the treatment space that you intend to use it in.

Square footage (of a room) = width x length (measured in feet)

After getting the exact number, consider which air purifiers that match their square footage coverage area to it. You can find this indicator on the product’s specifications (either under Sylvane product pages or “Manufacturer-Suggested Room Size” section).

Bonus:

For asthma or allergy sufferers, look for an air purifier with “Room Size for 4 ACH” specification, meaning the tool will make 4 times of air change every hour.

This model will assure you two things:

  •         Microscopic symptom-triggering allergens are kept filtering thoroughly while the air purifier is working
  •         Air is always clean during this time

And that is equivalent to you breathing more easily.
