Types of Air Purifiers – 2022 Informational Review

| Last Updated: January 30, 2022

Like food and water, air is also essential for improving the quality of our life. With the amount of pollution in the air and the contaminants floating around, clean air is now more essential than ever.

So if you are looking for a way to purify your air, then investing in an air purifier can be the perfect decision.

However, with the variety now available, which one type of air purifier is the best pick? Let’s find out!

What is an Air Purifier and How Do They Work?

Air purifiers are usually made up of multiple filters and a fan that sucks in air and circulates it. As this air moves through the filter, the particles and pollutants are captured, and the clean air is then pushed out again into the living space. Commonly, these filters are made from paper, fiberglass, fiber, and mesh.

These filters require proper care and maintenance in order to work efficiently. This means that apart from the cost of the unit itself, you also have to add in the cost of operating these products and replacing filters. How frequently you will have to change the filter depends on the purifier you are buying. Some filters are washable, and this makes them easy to maintain but are time-consuming as well.

Pros and Cons of Air Purifiers

Air purifiers have amazing advantages that help in improving your overall health. These units are no doubt exceptional, but they also come with some drawbacks as well. It is vital that you know of the ups and downs in order to make a well-known decision.

Pros of Air Purifiers

Helps With Breathing

The first and foremost advantage of these types of units is that they help in making sure you get clean air indoors. Apart from air being dirty due to smoke from cigarettes or outdoor conditions, you can also get unhealthy air due to a pet’s odor, urine, and dander. All of these things can contaminate the air and even cause allergies.

Removes Dust Particles

An air purifier has the precision of around 99.9%. This means it has the ability to remove almost all kinds of dust particles in the air. These particles can cause allergies and once removed, you can breathe clean and pure air.

Helps Your Skin

Having an air purifier significantly benefits your skin. Even if you have the best skin care products present, a high-quality air purifier can make your skin healthier and glowing more than ever. These purifiers help in improving your skin, preventing acne and even slowing down aging.

Cons of Air Purifiers

Requires Maintenance

Most air purifiers you get on the market make use of disposable and replaceable filters. This means that you can end up wasting a lot of money on buying replacement filters. They require proper care and attention along with regular maintenance so you must be sure that you can take on this hassle.

Ozone Air Purifiers Produce Ozone Gas

Many units available on the market are ozone air purifiers. These units tend to emit ozone gas and exposing this gas to your body can be harmful. It can cause chest pain, shortness of breath, and even cause persistent coughing.

True HEPA Purifiers

True HEPA Purifiers make use of HEPA technology which is an acronym for High-Efficiency Particulate Air. This technology has been used for many years in order to filter out particles. HEPA filters meet the standard of trapping around 99.9% of particles that are larger than 0.3 microns which can’t be spotted by the naked eye.

These HEPA filters are made from fine, fiber-like material and can last for around two to four years easily. These purifiers are very effective at trapping airborne particles but they do not remove odor, gases, and other chemicals.

Ozone Air Purifiers

Ozone Air Purifiers tend to clean your air and at the same time intentionally create ozone gas. Even though many units tend to claim that this gas is safe, the truth is, excessive exposure to this gas can ignite symptoms of asthma. For this reason, many air purifiers using this technology advise consumers to leave the room when using this unit.

Many different brands present in the market vary in the amount of ozone they produce. So while these purifiers do clean the air, they are not ideal for use throughout the day.

Activated Carbon Technology

Activated Carbon is a type of processed carbon that is extremely porous and has a large surface area of absorption. The pores present on this filter are of molecular size and can absorb very well. This makes activated carbon purifiers effective for capturing pollutants including odors, gases, tobacco smoke, chemical emissions, and other airborne particles.

Air purifiers using activated carbon filters are very useful for people who deal with multiple chemical sensitivities and is a safe technique for cleaning the air. These air purifiers are ideal for babies, adults, and even older people.
