Airborne allergens are an ugly part of life, and 99 percent of these are invisible to the naked eye. As someone who frequently suffers from the effects of hay fever, life sucks when you are constantly experiencing a runny nose, sensitive eyes and an annoying cough which just won’t go away.

While it’s almost impossible to tackle the problem when you are outside, you can do something about it at home. This is where HEPA air purifiers come in. They contain filters made of many layers of fibers that trap harmful air particles as air is drawn into the filtering system. Once the particles are trapped, the air purifier blows back into the room the filtered clean air for you to breathe in. All homes contain airborne allergens that the eye cannot see, such as pollen, dust and even fecal matter from dust mites.

Having an improved air quality standard in your home can be beneficial to your health. If you suffer from allergies, you know the importance of breathing air free of pollen, dust, pet hair and other allergens. A HEPA air filtration system can remove those particles from the air at a higher efficiency than other filters and improve your quality of life.

In this article, we take a look at some of the most popular and best rated air purifiers that you can buy to keep your air clean and fresh.

Coway AP-1512 HH Mighty

The Coway AP-1512 HH Mighty is consistently listed among the top-ranked and highest-regarded air purifiers on the market — and with good reason. 
It’s reasonably priced for how well it works, it’s one of the quieter machines of its size, and it has most of the features we’d want in an air purifier, including a programmable timer, several fan speeds and a filter indicator light.  
Replacement filters are fairly cheap and energy costs relatively low, which makes the Coway one of the least expensive air purifiers of its caliber to maintain year to year. 
Finally, the Coway AP-1512 HH Mighty is easy on the eyes. It comes in sleek black or white and is relatively compact compared with many other purifiers of similar performance, so it simply fades into a corner.  
The Coway Mighty is one of the only purifiers we considered that has an ionizing function. The effectiveness and safety of ion filters is questionable (due to possible ozone production), but you can just turn this function off.

  • Covers up to 361 sq.ft

Molekule Air Large Room Air Purifier

The award-winning Molekule Air combines a sleek design with dual filtration. Its pre-filter is designed to capture large pollutants like dander, and its PECO filter destroys extremely fine particles. The manufacturer claims this second stage will destroy bacteria, viruses, and other pollutants that are 1,000 times smaller than those that the average air purifier can handle. The PECO technology that Molekule uses may be innovative, but this also means that there’s less science attesting to its efficacy compared to standard HEPA filters. 

The National Advertising Division ultimately recommended that Molekule discontinue certain claims on PECO superiority, non-quantified pollution elimination claims, and allergy and asthma symptom relief, but maintained that it’s able to destroy pollutants at a molecular level and break down small allergens.

Nevertheless, the Molekule has thousands of user reviews attesting to its ability to clean their air and reduce respiratory issues, so you may want to consider giving it a try if standard HEPA filters haven’t done the trick for your symptoms. If you don’t want to spend a whopping $800 for spaces up to 600 square feet, the Molekule Air Mini is good for 250 square feet and costs half as much.

Air Purifier Buyer’s Guide and FAQs

Size – You may be better off if you purchase an air purifier that works just for your room size. An air Purifier’s scope of functionality is usually measured in square feet. Knowing your room size, you can purchase one which will fit in.

Maintenance – This is dependent on the type of air filter in question. Maintenance of air purifiers mostly has to do with the screens. Some air purifiers require that the filters are maintained by way of either washing them or a total replacement. This is done every 3 to 12 months on average. Filter lights on some air purifiers notify the users on when the filters need to be maintained.

Filter Availability – Air filters are a core part of any air purifier. It is the filter that traps in the different particles and keeps them away from human consumption. Most air purifiers are indeed highly durable. Nevertheless, one filter cannot last the entire lifespan of the air purifier. It needs to be replaced as per the manufacturer’s recommendations. Sometimes 3 months interval, 6 months interval, a year or two. An air purifier that would last and not dwindle in performance should have readily available filter replacements.

Fan Speed – This is important as it helps in pulling air into the air purifier, then it traps all available particles. The fan then aids in the circulation of purified air around the room.
