Best Air Purifier – Buying Guide

Over 50 million people in America alone suffer from asthma and allergies. With widespread pollution and contaminants in the air, it can be tremendously difficult to breath properly even indoors. This can lead to a great deal of discomfort and serious health issues if the contaminants affect the normal function of one’s lungs.

best air purifiers for allergens

Allergens in the air can ruin your day

Unfortunately, the majority of contaminants which compromise people’s ability to breathe are not visible to the naked eye. Whether inhaling smoke, bacteria, dust, mold spores, or any other number of harmful particles, many people are simply unaware that their indoor air quality has been compromised before it is too late. For this reason, the market for indoor air purifiers has been growing exponentially.

Home air purifiers are devices used to clean the air of pollutants that are not visible. They come in a wide variety of types, shapes, and sizes. In addition, there are several different filtration systems which have differing levels of efficacy. In short, it can be difficult to know which air purifier to buy, as the market has become crowded with dozens of different variations. In this review, the best air purifiers will be reviewed to inform our readers and they can get help finding good air purifier.

How Do Air Purifiers Work?

Generally speaking, air purifiers operate by using filters to clean the air in a given space. Most purifiers will sit in the corner of a room and filter the air as it cycles through. When the air passes through the purifier, it must travel through very fine sieves. Depending on the quality of the purifier, this sieve will filter out most of the harmful particles in the air, leaving it fresh and safe for breathing.

How air purifiers work (Courtesy of Holmes)

There are two important factors which determine how effectively the purifier will clean the air in a given room: the micron-trapping filter, and the room capacity. Microns are the unit of measurement used for air purifiers. While humans can only see objects larger than 10 microns, proper air filters should trap pollutants that are 0.3 microns or larger. The room capacity refers to the purifier’s ability to cycle the air. Repeated cycles result in greater filtration, as particles which slipped through the filter on a first pass will be caught in subsequent passes. Naturally, superior purifiers are required for larger rooms.

Given that air purifiers are filtration systems, they do require some maintenance and cleaning. Different models have different requirements, but the filters in air purifiers must be routinely cleaned to ensure consistent function.

Common Types of Air Purifier Filters

While there are certain industry standards, there are several distinct types of air purifiers. Each type comes with its own unique features, benefits, and drawbacks. Different purifiers will be better suited to different homes and needs. Here are some of the most common types of air purifiers found on the market today:

HEPA Purifier Filters

HEPA stands for High Efficiency Particulate Air. These filters are the most common in the industry and have set the standards for filtration efficiency. Essentially, these filters are created by folding a very fine material many times, resulting in a surface which has tiny openings for air to pass through. As the purifier’s fan pushes the air through the filter, contaminants are caught in the material.

The Holmes AER1 is an example of a HEPA filter

These filters are highly popular because of their effectiveness and lack of harmful by-products. They are able to filter 99.97% of air particles, making a dramatic effect on the quality of the air in a room. While these filters are highly effective at ridding the air of bacteria, dust, and mold spores, they are often unable to address odours.

Activated Carbon Purifier Filters

These filters are composed of many small, highly absorbent pores that are very effective at trapping smoke and gasses. They also absorb formaldehyde and perfumes. For this reason, Activated Carbon Filters are one of the most popular choices for individuals who suffer from asthma or allergies related to odours.

Activated charcoal filters for a Honeywell air purifier

Those who suffer from asthma and are primarily concerned with chemicals and gasses should strongly consider Activated Carbon. However, these filters are slightly less effective at cleaning the air of dust and bacteria than HEPA filters.

UV Purifiers

UV technology can be an effective way to help clean the air of germs, bacteria, and viruses. These filters come equipped with a UV bulb which shines on these contaminants as they pass through the filter. UV rays are highly effective at destroying such harmful microorganisms.

While UV filters are outstanding at purifying the air of viruses and bacteria, it is important to note that they are not effective when it comes to removing dust particles from the air. For this reason, good quality UV filters will also come equipped with HEPA or Activated Carbon filters to ensure that the air is completely fresh and safe.

Negative Ion Purifiers

With Negative Ion purifiers, charged particles are sent into the air in the room. These particles attach to contaminants like dust, giving them added weight. Due to the added weight, the contaminants are forced to settle on walls, ledges, and other surfaces. These purifiers do not come with a filter.

The PowerLead SPA 005 is a Negative Ion Purifier

This particular type of purifier is unique because it does not actually clean the air. Instead of trapping the contaminants, it simply forces them to fall to surfaces. While this can prevent them being breathed in, the contaminants eventually become free and circulate again. It therefore need to be used i conjunction with a vacuum cleaner.

Ozone Purifiers

These purifiers operate by releasing ozone into the air. It is believed that ozone will reduce the amount of bacteria in the air. However, it does not trap dust or other particles, and must therefore be used in conjunction with another filter. These filters are often not recommended by experts because of the harmful effects of ozone on the body.

 

The Benefits of Air Purifiers

Cleaner Air

best air purifier for tobacco smokeNaturally, the main benefit to purchasing an air purifier is cleaning the air in a given room. Ridding the air of pollutants is of benefit to everyone breathing the air. These purifiers are especially effective, however, for individuals suffering from asthma, allergies, or other respiratory issues. High quality purifiers are often able to eliminate over 99% of contaminants in the air.

Convenience

The powerful purifying effects of these filters does not require a large, bulky machine. Instead, many quality air purifiers are only 10 pounds and can be easily carried with a handle. For more heavy-duty purifiers, wheels are usually attached to make transportation simple. As well, they are usually easy to store in the corner of a room or on a small table.

Versatility

With so many purifiers on the market, every individual will be able to find the filtration system that is tailored to their own needs and budget. Whether looking to rid the air of dust, bacteria, viruses, or a wide range of particles, buyers will be able to find a purifier that is right for them. As well, there are a wide range of prices for purifiers, allowing people on a budget to enjoy cleaner air.

The Drawbacks of Air Purifiers

Maintenance

While air purifiers with HEPA or Activated Carbon filters are highly effective at trapping pollutants, this means that the particles once floating in the air are trapped in the filter. In order for the purifier to continue operating, filters must be cleaned or replaced regularly. Each purifier will have different requirements, but HEPA filters generally need to be replaced annually.

Safety

As a result of the technology included in some purifiers, ozone may be released into the air. This can be damaging for the lungs, which is why many health professionals recommend avoiding Ozone Purifiers.

 

What Features Should Buyers Look For?

Ultimately, the most important consideration to make when purchasing an air purifier is one’s own needs. An individual’s allergies, respiratory conditions, room sizes, and budget will determine which purifier is best-suited for them. Luckily, as stated above, there are so many purifiers on the market that everyone can find a suitable model. However, there are some common features which can help buyers know what to look for in a quality purifier.

Fans

Most high-end air purifiers use a fan to ensure that the air in a room is being circulated through the filter regularly. As well, superior models can adjust the speed of the fan according to the time of day, settings, or even the amount of dust in the air. More powerful fans are required to circulate the air in larger rooms, which is why high-end models often include adjustable fan speeds.

Sensors

best air purifiers allergies

Smoke sensor

Often, quality air purifiers will come equipped with sensors which allow it to automatically clean the air and alert the owner when the filter is full. Dirt sensors are highly effective in that it allows the purifier to adjust its speed according to the amount of pollutants in the air. Servicing lights are highly useful as the purifier will alert the buyer when the filter has become clogged. This is important, as the purifier cannot clean the air without a functioning filter.

Convenience

It should not be a hassle to clean the air in a given room. Good air purifiers come equipped with a variety of features to make the process easy for the buyer. These include handles for easy transportation, timers to allow the purifier to clean the air before everyone arrives home from work, and remote controls for convenience when adjusting fan speed.

Conclusion – Best air purifiers

Buying an air purifier can be one of the most important decisions an individual makes for their home. Living with pollutants and allergens in the air can have a very detrimental effect on one’s quality of life. In order to live the healthiest and most comfortable life possible, breathing clean air is an absolute must.

best air purifiers reviewsAir purifiers come in a wide variety of types. These include HEPA filters, Carbon Activated filters, ionizers, and UV filters. HEPA filters have set the industry standard for filtering contaminants such as dust, bacteria, and mold spores. Activated Carbon filters are also highly effective filters which can tackle perfumes and odours. Ionizers use ions to remove contaminants from the air. UV filters shine UV light on the air passing through the filter in order to eliminate viruses.

The best models often include a combination of these. With several different filters in a single unit, buyers can look forward to air that is clean, safe, and odour free. In addition, high-end purifiers often come equipped with pre-filtration systems which provide an extra layer of cleaning for the room’s air.

Ultimately, purchasing the ideal purifier depends on the specific needs, health, and budget of the buyer. In addition, the size of the room in which the purifier will be placed is an important consideration as stronger fans are required to circulate greater amounts of air.

It is important to purchase purifiers only from reputable manufacturers, as some purifiers leak ozone which can be devastating to one’s health. Each of the purifiers listed above are of the utmost quality and are built by companies which have a reputation for creating quality products. Purchasing an air purifier from one of the brands listed above is an excellent way to achieve healthy, clean, and fresh indoor air.
