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.

How to Buy the Perfect Air Purifier

The air within your home can be every bit as polluted as the air outside. Because most of us spend more time indoors than out, considering the quality of our interior atmosphere is a good way to protect our health and avoid respiratory problems.

An indoor air purifier can create cleaner, healthier air for homes, offices, coffee shops, medical offices and more. If you are considering improving the interior environment of your location with an air purifier, there are some things you should know about these devices.

In the following article, we will cover all the things you need to know to choose the right air purifier for you.

There are many different types of air purifiers available and each will serve a very specific purpose. Some of these will function better in your environment than others and some may even be a bad idea for your specific situation. Here is what you need to know:

Air Purifiers with Mechanical Filters

These air purifiers feature pleated filters and fans to pull air from the environment and remove airborne particles of up to 0.3 microns in diameter. A top-of-the-line mechanical air purifier will be able to remove as such as 99.97% of airborne pollutants including smoke, paint fumes, etc. Some of these also feature HEPA filtration which can remove dust and larger particles from the air. Be careful of those filtration systems that say “HEPA-like” or “HEPA-type” filters. These can’t be expected to provide the same results as a true HEPA filter.

These do have certain limitations, however. They are costly to maintain and can’t eliminate gases or certain odors. They may also cost as much as $200 but a decent option may only cost about $80.

Activated Carbon Filters

Unlike the mechanical type filters, activated carbon filters can capture odor-carrying molecules right out of the air with their charged carbon filters. While they may not be a suitable option for treating formaldehyde or ammonia, they can remove certain gases from the air as well. Activated charcoal filters are not effective against airborne particles, which is why many of these will also be equipped with a pleated filter.

It is important to note that the activated charcoal filter will need to be replaced more frequently — 3-4 months — than the pleated filter — 6-12 months. So, you will need to plan accordingly. An average activated carbon filter will typically cost about $50.

These filtration systems produce ozone. Ozone is a chemical that is released into the atmosphere to react with certain compounds and change their chemical composition. While this is effective against certain pollutants, some experts agree that these are not suitable for indoor use. This is because the levels of ozone needed to improve the air quality indoors will exceed what could be considered healthy.

Electronic air purifiers

Electrostatic precipitators and ionizers will provide a charge to the particles in the air so that they stick to electronic plates. Much like the ozone air purifiers, there is not much evidence that these are actually effective for improving indoor air quality. As a matter of fact, you would do just as well to use an indoor water fountain.

UV Germicidal Irradiation

Some manufactures of air filtration systems claim that a UV lamp is the best thing for killing mold spores, viruses, bacteria and other airborne pathogens. While mycotoxins, the harmful toxins produced by mold colonies, can be controlled with UV light, many spores and bacteria have been found resistant to UV radiation. As a component of a larger air purification system, UV filtration may be a good idea; especially in regions with considerable humidity. But as a stand-alone option, it may not be very effective.

FAQs On Getting the Best Air Filtration System for You

Now that you know a little more about the filtration and purification systems on the market, here are some of the questions you should ask yourself when choosing the right option for your home.

1. Why Do I Need An Air Purifier?

Air purifiers are a good way to keep the air quality at a healthy level. Here is a simple guide for choosing the right option for your home or office.

Allergies — if you are suffering from allergies, you will need an air purifier designed to remove allergens from the air. The best sort will feature a HEPA filtration system

Asthma — asthmatic reactions can be triggered by gases, odors, and chemical pollutants, The best option here would be the activated charcoal option to remove these pollutants. The addition of a HEPA filtration system will ensure that pollen and other particulate matter is removed as well.

Smoke — there are air purifiers with HEPA filters specifically designed for removing smoke from the environment. These are fitted with HEPA H13 filtration systems which can remove considerably small particulate matter, even smoke and certain fumes. Whereas the HEPA H11 can remove particles as small as 0.3 microns, the HEPA H13 can remove particles as small as 0.1 microns.

Pets — homes with pets will need a specially designed filtration system that will pull pet dander and certain odors from the air as well. These special filtration systems will use a combination of purification and filtration systems to accomplish this task. Typically, activated charcoal supported by a HEPA 13 filter is more than adequate.

2. What Size Air Purifier Do I Need?

You will need to measure the area of your room before choosing your filtration system. This way you will be sure that the device you have selected will effectively purify the entire space. Look for the ACH (Air Charge per Hour) rating. This indicates the number of times the filter will filter all the air in the room in one hour.

3. What Features Do I Need on My Air Purifier?

Some of the extra features that will improve the functionality of your air purification system include:

Energy Star Rating — The EPA issues Energy Star ratings to those air filters that use less energy. This can save you money as well

Connectivity — some air filtration systems can be activated and interfaced through your mobile device. This makes things terribly convenient.

Air Quality — these indicators will provide you with a status report in real-time, this way you can know exactly how your purification system is working.

Other — other useful features include fan speeds, handles, remote controls, and filter change indicators.
