The Best Air Purifier for 2021

If you have hay fever, dust allergies, or asthma, you are probably very well aware of the significance of having fresh and clean air at home. And even if you are perfectly healthy, it always helps getting to breathe clean air at all times, right?

Air purifiers are ingenious devices that help clean out the ambient air from pollutants, allergens, germs, and other harmful debris and microorganisms. Having an air purifier is essential if you live in a heavily polluted urban area.

It is also indispensable if somebody in your household suffers from allergies, asthma, or other respiratory problems. An air-cleaning device is also highly recommended for households where there are small children, elderly people, or people with health problems or weak immune systems.

Homes where there are pets, mold, kitchen fumes, smokers, or other pollutants, can also benefit from a good quality air purifying device.

Some common pollutants which can be found in the air that you breathe at home include different fungi spores, molds, viruses, bacteria, pollen, volatile organic compounds, dust, smoke, chemical fumes, and pet dander.

Thankfully, a good air purifier is able to remove some or all of these pollutants from the air you breathe at home via different cleaning and filtering systems and blows back the purified, fresh air inside.

Final words

Studies show that the sales of air purifiers worldwide has been rapidly increasing since 2010, and the forecasts are that it will continue growing in the next 5-10 years.

The main reasons for this tendency include:

  • The growing awareness of the impact of indoor pollution on the health
  • The increased environmental pollution due to harmful emissions
  • The growing number of people suffering from allergic respiratory, skin and other disorders
  • The increasing quality of the HEPA and other modern filtering systems

The different air purifiers use different air cleaning systems and technologies to filter out the ambient air. This can include filtering, burning, ionizing or irradiating the air.

Here are the most common air purification methods used by manufacturers today:

  • Thermodynamic sterilization
  • HEPA filters
  • UV germicidal irradiation
  • High-efficiency MERV 14
  • Activated carbon
  • Ionizer purifiers
  • Polarized-media air cleaning
  • Photocatalytic oxidation
  • Ozone generators
  • Titanium dioxide technology

As you can see, the variations of the air purifiers are so many that it is really tough to choose the perfect one for your needs.

What you need to consider when picking an air purifier is what exactly you will be using the purifier for.  Is it to eliminate odors from chemicals, pets or cigarette smoke? Is it to minimize the airborne allergens in the air? Will you be using it to kill off germs, viruses, bacteria, and other harmful microorganisms? Do you have somebody in the household who has special air quality needs?

Once you sort this one out, you can pick the air purifiers which are rated best for the purpose you need them.

Then you can start sorting the air purifiers by the capacity of the rooms they can handle, as well as by the size of the unit.

The number of cleaning and filtering systems used, as well as the specific types of filters utilized by the purifier, is also essential. You need to choose the right filtering system which will satisfy your needs and meet your expectations.

Another crucial feature is the control and setting of the unit. Does it have an easy to use control panel, a remote control, or maybe a mobile app to make monitoring and controlling it easier?

Also, look for features such as automatic switching on if a lowered quality of the air is detected, an automatic switch to sleep mode when it gets dark, a dimmable indicator and lights, and other useful features.

Of course, the price is probably the most decisive factor. Remember to check out the price tags not only of the unit of your choice but of the replacement filters, light bulbs and others as well. Plus, do some calculations about how much the unit will cost you per year given the recommended period for replacing the filters.

Don’t forget to look at the warranty period, as well as the usefulness and availability of customer care, replacement part, and service.

All of these pointers should help you make up your mind about the right choice for an air purifier.

In today’s world of heavy traffic, pollution, and the growing number of children and people suffering from allergies and respiratory problems such as asthma, investing in a good quality air purifier is a must. This is especially true for people living in big cities, beside busy roads, or houses where there are smokers, pets or people with compromised immune systems, respiratory problems, eczema, and others.

After all, the air that we breathe is crucial for our lives, health, and wellbeing. So, why not spend some of your hard-earned money on a good quality air purifier, instead of spending it on medicine and hospital bills later instead.
