Some owners have had their unit for more than 5 years and it is still going strong. But thats not what we love about this. One of the most expensive things about air purifiers are the filters.

Just wash them, dry them, put them back, and the air purifier is good to go again. Plus, this is Energy Star rated so you dont have to worry much about power consumption.
However, the HEPAClean filter used by the manufacturer is not a true HEPA filter and is only passable at removing smoke particles and odor. Also, it makes use of a built-in ionizer.

- Smart sensors

However, in comparison to all our other picks, this unit does require you to put out some serious change. We admit that one of the reasons we picked this baby is due to the way it looks. It definitely isnt like any other air purifier weve seen. But thats not why it has a high price tag.
This unit is very high tech; you can control it with your smartphone AND Amazon Alexa. You can even get real-time reports on air quality. But thats not all. Aside from cleaning your air using a 360 Glass HEPA filter that has a layer of activated carbon granules, this machine also cools you off in the summer by functioning as a fan.

The HealthMate has 3 fan speeds and 360-degree intake. The body is solid, welded-steel with a durable powder coating. It even comes with casters to make it easy to move from one room to another.

Choosing The Best Air Purifier The Ultimate Buying Guide
If you want to breathe easier and enjoy fresh air, theres one good way to do it get an air purifier. A good air purifier minimizes the number of irritants/pollutants in the air. However, not all air purifiers are made equal so choosing the best one that suits your familys needs may not be as easy as it looks. To help you out, weve written a short but pretty informative guide on the specifications and features you should be on the lookout for.
Types of Air Purifiers
If youre looking for an air purifier for your home, there are two types for you to choose from portable and whole-home air purifiers.
Portable Air Purifiers: They are usually designed for cleaning the air in no more than one room at a time. Most air purifiers belong to this category and weigh from 10 to 25 pounds. Some feature a handle to make it easy to carry from one room to another. Some can stand on the floor while others can be placed on a table. Others may even feature wheels for increased portability.
Whole-Home Air Purifiers: On the other hand, they are attached to the ductwork or furnace inside the home so that it cleans the air that passes through. This type of air purifier is usually bought when you are building a home or buying a new furnace.
What kind of Filter should Your Air Purifier have?
Naturally, your air purifier should have at least one filter. But some actually have two or three workings together which means you dont need to change the filters as frequent. And this equals less money spent over time.
Now, the primary filter in a good air purifier is the HEPA filter. HEPA stands for high-efficiency particulate air which can catch really incredibly small articles. In fact, according to the standard, a True HEPA filter must capture up to 99.97 percent of particles that are as small as 0.3 microns.
Some portable air filters come with a pre-filter that serves as a bodyguard to your primary filter. Its purpose is to catch the bigger particles which includes dust. The presence of this pre-filter lengthens the life of your HEPA filter, especially if you change it often.
Some air purifiers even have a second pre-filter which is also used to lengthen the life of the HEPA filter by catching small particles before it reaches the primary filter. It may also be used to catch odor molecules. For example, the Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier makes use of a six-filter system for cleaning the air.
Carbon filters usually require changing every three months while the primary filter requires changing once a year. Take note that true HEPA filters are expensive. The cost of filters generally ranges from $10 to $500. Fortunately, some filters are now washable which means you can use them multiple times before requiring replacement. The Honeywell HFD-120-Q QuietClean Tower Air Purifier uses permanently washable filters.
Should the Air Purifier Use an Ionizer?
An ionizer makes use of electrically charged ions to attract pollutants and particles in the air. However, some ionizers produce low levels of ozone which, according to experts, is a possible lung irritant. So, its probably in your best interest to get a purifier without this feature or one that can be turned off like the Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier.
CADR stands for a clean air delivery rate. It measures how fast an air purifier can clear the air of three of the most common air pollutants dust, pollen, and smoke. A higher rating means a better air purifier because it cleans more air per hour. Air purifiers that have a CADR rating of 350 and above are excellent while those rated as less than 100 are of poor quality. Out of all of our picks, the Honeywell True HEPA Allergen Remover has the highest CADR rating (300 for pollen and smoke, 320 for dust).
What size should I get?
When choosing an air purifier, you need to consider the volume capacity that the manufacturer either specifies or make use of the measurements they provide. Below are some of the measurements used to help you determine size.
Square Footage: Is the size of the room that a manufacturer recommends can be covered by an air purifier. To ensure that your air purifier doesnt get overstressed, get one that has a bigger coverage compared to the room that it will stay in.
CFM or Cubic Feet Per Minute: This is a rating used by some manufacturers to measure how much air is processed by the purifier every minute. Using this figure, you can calculate how many times the air purifier will suck in all of the air and purify it.
ACH is Short for Air change Per Hour:This measures how often the purifier will draw the air into the room through it. For example, an ACH rating of three would mean that the purifier would be able to draw the entire volume of air in the room three times per hour.
What other Features should I Look at?
Most air purifiers draw in the air by using a fan. However, some manufacturers opt to not include one to make a unit run more quietly. Instead, this kind of air purifier will just rely on nature cleaning what air passes through the purifier due to the air circulation in the room. If you want an effective air purifier, youll need to purchase one with a fan.
Youll also want to consider multiple fan speeds. This way, you can adjust the level of noise and effectivity of your air purifier according to your needs. You can set it to run slower while youre sleeping or run higher during times when extensive cleaning is required such as during pollen season.
Some air purifiers come with timers that allow you to schedule how long the air purifier will run. You can even set the air purifier to run before you use a room so that you get clean air when you walk in. The Honeywell True HEPA Allergen Remover, for example, can be scheduled to turn off after 2, 4, or 8 hours of running.
A servicing indicator lets you know if you need to clean the air purifier or replace the filter. This also ensures that your air purifier stays effective and efficient. A full filter may cause your air purifier to stop working. Most of our picks, including the GermGuardian AC4825 3-in-1 Air Purifier, feature a filter change indicator.
Other extra features that you might be interested in carrying handles, dirt sensors, and remote controls. Carry handles enables you to easily move the unit from one room to the next while remote controls can let you program or adjust the settings of the unit from the other side of the room. A dirt sensor is a feature that enables your air purifier to detect the level of dust or dirt in the air and automatically adjust its fan speed accordingly. This particular feature can be found in most of our picks, including the Winix 5300-2 Air Purifier.
