2020 Best Air Purifier for Pets Guide for Pet Dander, Odors and Hair

This can cause health issues, particularly for allergy afflicted people. Actually standard airflow generally does not make it possible for sufficiently providing a solution. For allergy sufferers, air purifiers in the household or at least in the most frequently used living spaces are already standard.

An alternative is a free-standing air purifier that permanently removes up to 99% of the particles from the room air. However, many consumers are not sure how helpful or even harmful an air purifier is. We would, therefore, like to answer the most important questions about air purifiers.

How does an air purifier work?

The operation of an air purifier is very simple. The room air is usually sucked in via a type of fan and through different filters, e.g. Activated carbon or HEPA filter. These collect the finest particles and pollutants. The cleaned air is then led out of the device. Devices are also available that humidify the air at the same time. At this point, however, we do not want to address them.

Is ventilation still necessary with air purifiers?

Yes. Despite air purifiers, you should continue to ventilate regularly in all rooms. The air that is cleaned in the device is not fresh air but is recycled. The proportion of carbon dioxide in the room air, therefore, does not decrease. You will feel tired after a while. After briefly ventilating (better than tilted windows!) You will feel better again.

How does an air purifier with a HEPA filter work?

A HEPA filter (High-Efficiency Particulate Air Filter), also called a particulate filter, consists of glass fiber filter mats with a particularly effective particle filter that removes suspended matter up to 0.1 microns from the air.

HEPA filters are preferred by allergy sufferers e.g. used in animal hair allergy. But many other particles are also permanently removed from the room air, e.g.

  • Asbestos,
  • Bacteria,
  • viruses,
  • Dust or dust mites and mite eggs,
  • pollen
  • Smoke or
  • dust particles containing pollutants.

The disadvantage with HEPA filters is, however, that very small particles such as smells, Gases or particulate matter can only be filtered to a limited extent.

When buying an air purifier with a HEPA filter, make sure that it is in extra housing, as otherwise, you expose yourself to the risk of inhaling unhealthy or even toxic particles.

Who has the choice?

As you can see, choosing the right air filter is harder than you thought. We advise you to first consider the following:

  • What do you need an air purifier for?
  • Do you suffer from health problems?
  • What type of filter do you prefer?
  • How big is the room in which you want to use an air purifier?

We advise you, especially if you suffer from allergies, to use an air purifier with a HEPA and activated carbon filter. These are ideal for “normal” needs. However, if you have special requirements or require a very fine filter, take a closer look at the ionizers.

An air purifier in closed rooms is always recommended. Not only to relieve symptoms but also to improve well-being. Many people have had a good experience with this, which is demonstrated not least by the increasing production figures from providers such as Blueair, Dyson, and others.
