Rabbit Air MinusA2 HEPA Air Purifier Review

The MinusA2 SPA-780N is a quality product that heads the class in most categories in purifying the air of pet dander, smoke, or other contaminants. This HEPA air purifier traps air contaminants like dust, pollen, pet dander, mold, odors, and many others. It cleanses the air using an advanced 6-stage process. Besides purifying, it also deodorizes the air, making living spaces of up to 815 sq.ft./ 75sq.m fresh 24-7.

The 6 stages begin with a pre-filter that collects large-sized particles. These include dust and common allergens. The medium filter traps smaller sized particles, but larger than a micron in size. These include pet dander, mold, and pollen. The third stage has a BioGS HEPA filter. This stage eliminates pollutants that are 0.3 microns in size, which further cleanses the air of common allergens.

The fourth stage involves a customized filter. Depending on the targeted use, one could opt for a toxin absorber, odor remover, germ defense, and many others. The fifth is the charcoal-based activated carbon filter that absorbs common household odors, chemicals, smoke, and harmful gases from paints, cleaners, detergents, and so on. The final stage involves negative ions generation. When they are released into the air, they tend to be healthy to the body and enhance indoor freshness.

The process summarizes the efficiency of this system in eliminating all kinds of air contaminants and odors. Additionally, the air purifier has a user-friendly interface and can be connected to devices via WiFi using a RabbitAir application. It is also compatible with Alexa, making it quite convenient and easy to use. Moreover, the device is extremely quiet and comes in a stylish rectangular body, available in black and white options.

It is a great option for large living spaces and can either be wall-mounted or placed as a stand-alone device. The only disadvantage would be the production of Ozone, though the levels still fall well below the recommended levels by the California Air Resources Board.

Molekule Air Large Room Air Purifier with PECO Technology Review

The value of squeaky-clean homes cannot be underestimated, including the quality of the air. The Molekule Air Purifier is one of the more expensive models we looked at to see how it measures up to the other top models. This air purifier uses advanced Photo-Electrochemical Oxidation technology to eliminate air pollutants like mold, bacteria, viruses, VOCs, and allergens.

The technology oxidizes organisms and other organic chemicals in the air using a nanoparticle coated filter, destroying them completely. It is efficient for use in large rooms up to 600 sq.ft/ 55 sq.m. This makes the purifier ideal for social rooms like lounges, family rooms, living rooms, and even large master bedrooms. It uses a touch-screen display control, which can be linked to android and iOS devices. This feature makes the device user-friendly and convenient to use. Additionally, it does not emit ozone but gets rid of it, making breathable air devoid of harmful microbes and gases.

The purifier is also portable, which makes it flexible and adaptable for almost any situation. Quickly moving it between rooms is a simple exercise. Made of machined aluminum, the Molekule Air purifier is sleek and versatile. It fits seamlessly into the interior design of any room, regardless of the color scheme therein.

The PECO filter used in air purification lasts for an average period of 6 months for average use, while the pre-filter will generally need replacement after every 3 months. The good news is that the package comes with 2 pre-filters and 1 PECO-filter, and additionally, automatic filters are available for delivery by the manufacturer. This is one of the best looking and feature rich air purifiers currently available. Unfortunately, other models outperform its ability to clean particles out of the air for less money. That doesn’t mean it is a bad purifier by any means. It just means that better deals are available for similar or better performance.

  • Minimal design makes for flexible placement
