Entering your home should feel like a breath of fresh air—literally. However, it is not always the case. There is nothing more refreshing than breathing fresh air, especially in one’s home. If you are able to keenly follow this guide, you will always have fresh air at your home. This guide is focused on the best air purifiers.

Air purifiers rid rooms of contaminants using either active purification, which converts chemicals and gases into harmless molecules; or passive purification, which extracts contaminants using a built-in filtration system.

Most air purifiers sold today fall into five categories based on their design: HEPA (passive), activated carbon (passive), an ionizer (active), ultraviolet germicidal irradiation (active), and ozone (active). Additionally, some models utilize two or more of these systems simultaneously.

AIR PURIFIERS BUYER’S

Type

Air purifiers come in two types: Room Air Purifier and Whole-House Air Purifier. The first one is arguably smaller and less expensive compared to the other one. To be sure about the type you’ll settle down with, you should be able to answer these questions.

Where are you going to use the air purifier? Who is going to use the purifier? In most cases, if your house doesn’t have a heating system, then it’s appropriate to settle down for a room air purifier.

Air Filtration Technology

Air purifiers employ different air filtration technology. HEPA technology is the most used air filtration option for most air purifiers. It is the best option of dealing with radioactive particles in the air.

These filters have a pleated surface area for trapping air pollutants of size 0.3 microns or more. Though HEPA filters are perfect, they tend to be costly because you’ll need to do regular replacement of about 12 to 18 months.

Other technologies that are usable include ULPA and activated carbon filters technology.

Size

Clean Air Delivery Rate (CARD) metric determines the size of the air purifier you opt for. The higher the metric, the more an air purifier is efficient. To ascertain the CADR for a specific room, you multiply its footage by 0.75

Features

Each air purifier has varied functionalities depending on the brand, model, and size. Among all air purifiers, a fan is one of the elements meant for sucking air in. The air purifiers without fans tend to work dismally, compared to the air purifiers that have fans.

Another main feature to consider is the servicing indicator. This unit will alert you to your next replacement of the crucial parts of the air purifier like the air filter.

Room Size

Room size is a crucial factor you need to bear in mind prior to purchasing any air purifiers. All air purifiers will have information about the square footage they cover; it is important to consider the square feet of the large room, or if you have high ceilings, you are wanting to use the air purifier in. If you purchase one that is too small, it will not work well and won’t provide effective cleaning.

Many air purifiers will speak of their air changes per hour and this is based on the maximum square footage they cover – you will never achieve this if your air purifier is too small for the room in which it is placed.

You will notice that many air purifiers speak of clean air delivery rate (CADR), which measures the cubic feet of air filtered per minute; so, the larger space you are needing an air purifier for, the greater the CADR required to provide effective air cleaning.

Airocide APS-200

B00F2MPBMS

The Airocide APS-200 is a filterless air purifier with a unique, attractive design. It has a rectangular shape with a cut-out in the middle. A fan draws air into the cut-out area, then that air is oxidized using a NASA-created process called photo-catalytic reaction. This technology allows the Airocide APS-200 to purify particles that are too small for a HEPA filter to trap. Unlike HEPA filters that trap pollutants, the Airocide APS-200 actually destroys them. This air purifier can eliminate volatile organic compounds (VOCs) from paints, cleaning products, air fresheners, and more.

PROS CONS
  • A darkness-triggered auto-adjustment option
  • none
  • Two-speed settings
  • Sleek design

The Molekule purification system uses two filters: a “pre-filter” that captures larger particles like dust and hair, and a filter that breaks down pollutants at a molecular level. The second filter uses Photo Electrochemical Oxidation (PECO) technology. PECO uses light-activated free radicals to oxidize pollutants. While other air purifiers filter unwanted particles out of the air, the Molekule literally destroys them.
