Best Air Purifier

I think you’ll agree with me when I say:

It’s REALLY hard to choose the best air purifier with all the choices available!

Or is it?

Well, it turns out, that after years and hundreds of hours of testing & reviewing, we have strong opinions about what makes the best air filtration system: level of purification, efficiency, and maintenance, noise level.

What We’re Currently Loving

The IQAir Health Pro Plus (On special until end December 2018) has all the qualities and features, giving it an added advantage and an edge over its competitors. We love the fact that the IQAir Health Pro is quiet and that it cleans out pretty much every allergen in the air. It is different from the Honeywell air cleaners because it provides its consumers with 32% less noise. It also gives up to 25% more clean air and has 38% longer filter life. To makes matters even better, the purifier is currently the quietest high-performance product on the market. Don’t you love that?

It has the exclusive IQAir HyperHEPA filtration technology that traps particles of all sizes from viruses to pet dander to dust mites and other allergens including cigarette smoke. It is certified to filter 99.5% of all particles down to 0.03microns. These are the smallest particles that exist. IQAir is an educational partner with the American Lung Association.

What Are They?

Air purifiers assist in purging the air of particulate contaminants from your home especially if you own a pet or two. They help in also removing odor from the air by collecting and breaking down odors, although they may not remove all of it. Air purifiers and air cleaners may appear to be different, but in fact, they are necessarily the same and serve the same purpose. They both help to keep your indoor air clean.

How Do They Work?

Air purifiers use filters, ozone or electrical attraction to filter allergens and pollutants from the air. Air filters utilize fine sieves to filter particles like dust, smoke, allergens and other contaminants. The finer and better the sieve you use, the smaller the particles it traps.

But here’s the kicker:

The High-Efficiency Particulate Air (HEPA) filters which are guaranteed to capture 99.9% of airborne particles larger than 0.3microns set the benchmark for air filters. HEPA filters get rid of smaller allergens like dust, chemicals, asbestos, smoke, pollen and pet dander. The more times air passes through the HEPA filter, the cleaner the air becomes.

Why You Should Trust Us

What Features Did We Look At?

Most people today are turning to more organic and natural solutions for health issues such as allergies and asthma, and the easiest way to rid the air of these airborne contaminants is by using an air purification system. However, we admit that picking the right one for your house can seem like a daunting task especially when you do not know where to start.

We picked our top five based on the following features:

The Level of Purification

One of the first things to look out for when choosing an air cleaner is the standard of cleaning for each type. It means the clean air delivery rate (CADR) for the particular room. The standard developed by the Association of Home Appliance Manufacturers measures some cubic feet of fresh air that the product can deliver in a minute. The appropriate amount should be at least two-thirds of the square footage of the room.
National Institute for Occupational Safety and Health

Price

Price also need be one of the most critical consideration you make before purchasing an air cleaning product. You are also expected to budget within your range. However, when it comes to more efficient and productive models, it is without a doubt that it will be more expensive.

You also need to factor in the cost of replacement parts and filters for proper maintenance.

Warranties for specific products should also be considered carefully.

Pro Tip Price Maintenance

Quality

You can determine the quality of the device by how long it will last, how well it is designed and the issues that can arise due to frequent maintenance. You need to consider the air filters with a record of long-term use over products that spoil quickly or become less active over time, and the best way to know this for sure is to read consumer reviews.
PCO

Efficiency and Maintenance

How regularly the product will require maintenance needs not to be underestimated as well as its effectiveness. Some devices require less maintenance than others. Many also have the Energy Star rating that is vital to avoid unnecessary electric bills.

Noise Levels

Most air purification models use a fan to force the movement of air to work properly. These fans vary from one product to the other thereby resulting in various levels of noise. Some purifiers have adjustable fan settings to assist in controlling the noise levels. Others do not have fans thus making them noiseless. However, the downside to this is that the machine may be less efficient. Therefore, choosing a noise level that is acceptable to family members should be an important deciding factor.

Air Purifier FAQ’s

Q: How Do HEPA Air Purifiers Work?

A: Dirt, debris, and other impurities get into the washable pre-filter that traps the large and visible particles. Air then passes through the HEPA filter. The HEPA filter system comprises of millions of fragile fiberglass fibers that are combined to form a lighter material. During the manufacturing process, the best media gets rolled and pleated while the stuff is warm, to prevent any cracking. As air passes through these HEPA filters, allergens of various sizes, pollen, pet dander, mold spores, and dust get sucked into the small filaments of the screen. Most HEPA purifiers also feature a carbon filter to capture chemicals, odors, and gases. Once the dirt and debris pass through all the filtration stages, the now cleaned air is sent back into the room. We have the answear for this question to average ceiling height of a home.

Q: Where Should I Place My Air Purifier?

A: Most designs are for cleaning single rooms; so naturally, it will be a perfect choice placing it in the room you spend the majority of your time. It can be in your bedroom, living area, office or the playroom with your kids. You may also want to consider purchasing one with caster wheels that allows you to quickly move the unit from room to room to gain clean air anywhere that you spend your time.

Q: What Is CADR?

A: The CADR acronym represents a crucial measurement. It stands for Clean Air Delivery Rate. It a development of the Association of Home Appliance Manufacturers, and it indicates the volume of filtered air that it delivers. It is in three measurements – one for pollen, another for tobacco smoke, and the other for dust. The higher the CADR number is, the faster the unit filters the air.

In Summary

Having listed some but a few of our favorites, we do not argue the fact that there is no size-fits-all. The main aim of any air purifier is to assist in cleaning the air and getting rid of allergens and toxins making it very necessary for people with asthma or other allergies.
