Best Air Purifier 2019 – Review & Buyer’s Guide

TOP 10 BEST AIR PURIFIERS

Health Review Fairy is back with another top 10 list. See who made the running for best air purifier. You don’t have to be an MIT graduate to understand the importance of fresh and clean air. There are not enough synonyms to describe the magnitude of influence that clean air plays in our health. People have become so obsessed with leading a healthy lifestyle. You do so much to keep your health in check, so much exercise, diets, meditations, blah blah. But, there’s hardly anyone who takes the importance of clean air as a serious factor in leading a healthy lifestyle. In reality, everything you do revolves around two primary factors that ultimately dictate your health and ultimately your lifespan. These two primary factors are Clean Air and Fresh Water.

The fact that air comes free to us has somehow led us to undermine its vitality. The UN’s body “World Health Organization” has stated that 90% of the air that we breathe at present is “contaminated.” In fact WHO blames “unclean air” as the primary reason for causing “global health emergency.” Every NINE out of TEN people breaths contaminated air, which in turn has contributed majorly to the death of millions every year.

Improving the air quality on a global scale can only be described as “ideal” and something that looks more than an impossible task to achieve. But, luckily there are solutions that are available that enables you to purify the air you breathe. One of those solutions and a rather simple one are “air purifiers.”         

A proper and effective air purifier can help you remove up to 99.9% of the contamination present in the air. These contaminations include dust particles and impurities such as dust mites, pollen, spores, mold, etc. The working principle of air purifier is approved, and there are several studies that have successfully concluded the effectiveness of air purifiers. So in brief, air purifiers are a legit purification product, and not just another hi-tech money exhausting product

The LEVOIT PUR131 is bigger, and hence has more area covering functionality and offers more practicality as well. This, of course, comes with a cost, hence, the PUR131 cost more. The LEVOIT PUR131 incorporates every minor detail in the H123 purifier and give you a more “complete package.”

This filter stage takes care of about 85% of all the unwanted smells in the room 

Design 

The design of the LEVOIT PUR131 is absolutely stunning. It’s slim and slick, and its appearance completely defies its heavy weight.

Design  

The design of the Bissel air400 resembles a box-a rectangular and bulky box. But, that doesn’t mean it bad, right? i.e. unless you have some personal issues with boxes. The design and the layout are cleverly distributed. Unlike other air purifiers that squeezes all the controls and display on one particular surface, the air400 separates its controls and display in different surfaces 

The buttons for various controls sit on top, and they are intuitive and very easy to navigate as well. The air quality display is present on the right side, and they are large enough to be visible even at good distances 

Coverage Area

The Bissel air400 has effective air purification area of about 300-400 sq. ft, which makes it suitable for medium spaced rooms

  • Silent mode operation
  • Lightweight and portable
  • Intuitive display

10. Blue Pure 211 + Air Purifier 

Overview air purifier

The Blue Pure is the last air purifier product, but it goes without saying that “it is definitely not the least.” If you were to buy an air filter purely by its looks and design, Blue Pure 211 + would definitely be up there

It’s classy, and it has got all the performance in the world to back it up. But, the main reason to consider it would be its effective and unique filtering process 

The Blue Pure 211+ is available on Amazon for the starting price of $299.99   

Features 

  • The filter change indicator allows you to know when the filters need to be replaced for optimal efficiency 
  • The light automatically dims to  10% of its brightness after seven seconds of changing the controls of the purifier
  • The noise factor is comparatively less producing less than 31db in the lowest setting, which is ideal for sleeping 
  • The Blue Pure 211+ is extremely energy efficient. In fact one of the best products that feature such high energy efficiency consuming only 61W at the highest setting
  • The products come with a 2-year manufacturer warranty      

Filtration Process 

  • Preliminary Filter 

The preliminary filter, in this case, has an additional fabric filter, which of course enhances the filtering process. This filter doesn’t need replacement and can be vacuumed every 3-6 months

  • Particle filter 

The particle filter is a dedicated filter “design” for Blueair products. It performs the same function of the True HEPA filter, only more effective (as per Blueair claims). It can eliminate up to 99.97% of the air contaminations

  • Carbon Filter 

The carbon filter filters out the odour and makes your rooms smell better. This filter needs to be changed at regular duration (every six months)  

Design 

While the design of any products and whether you prefer it or not is entirely subjective, you are going to have a hard time disliking this one. The design is sleek, and it’s classy. You may regret keeping it on the floor. For a product that has good coverage area, the Blue pure 211+ is surprisingly lightweight

The build quality is also high-quality and doesn’t disappoint in that area. The main highlight is the outer filter which is available in different color options
