Best Air Purifiers Costco | Walmart | Amazon

Allergens that are airborne are a part of our daily lives, and around 99% of these are invisible. As a person that often suffers from hay fever, life becomes difficult when you have to constantly deal with sensitive eyes, a nose that runs all the time, and that annoying cough that just doesn’t go away.

While these issues are impossible to deal with when you are outdoors, there is definitely something you can do about it when you are in your home. This is when a HEPA air purifier comes to the rescue. These devices contain filters that consist of various layers that contain fibers which trap particles that are harmful in the air. This occurs when the air in your home is sucked into a filtering system.

As soon as these particles become trapped, these air purifiers will blow back clean and filtered air into your home, helping you to breathe easier. Every home is full of airborne allergens that you cannot visibly see. This includes dust, pollen, and fecal matter that comes from a common irritant known as dust mites.

Improving the quality of the air inside your home is always beneficial when it comes to your health. If you are one of the many people that is allergic to airborne allergens you will know how important it is that you breathe air that is free from pet hair, dust, pollen, along with other allergens. The right HEPA air-filtration system is able to remove these particles much faster than other types of filters and it will improve the overall quality of your life.

Today, we will give you more information on the best-rated and popular air purifiers to help keep the air in your home fresh and clean.

1. The Honeywell True Allergen Remover HPA300 – Editor’s Choice: Best Air Purifier

This purifier works on a 2-stage, mechanical-filtration process. It first pulls air through a pre-filter that contains activated carbon, and then the air passes through a HEPA filter. This device has enough power to purify the air in rooms of up to 465 sq ft. It also comes with an auto-off setting which is very convenient when you plan to use the unit passively in the form of a multi-room appliance.

Honeywell advertises that the unit is able to handle around 280 cubic feet of air every minute in a room that measures 465 sq ft. Or the unit is able to circulate the air in the room as much as 5 times in an hour according to AHAM smoke CADR (of 300) in a 465 sq ft room.

The self-monitoring function will alert you when it is time to replace the filters, while the panel at the front is removable which offers an easy way to replace the filters. The unit only weighs 21 lbs, which is beneficial as most of the purifiers in this class are much heavier.

Unlike many of the other types of air cleaners that are portable, the Alen BretahSmart comes with various customization options. If you are not happy about using a bulky unit in one of your living spaces, then this product may be the ideal option for you. The Alen comes with front-face plates that are interchangeable in 14 color options, which allows you to match the unit to the décor in your home. They even offer a cover that you can paint over.

In the technical department, the BretahSmart utilizes a 3-stage process in order to filter out pollutants. The air is drawn inside the unit from the back, which then passes over the pre-filter which encases its main HEPA filter. The air then passes out of this unit through an ionization field (optional) which you can activate from the Control Panel which is positioned on top of this system.

Alen allows consumers to choose from 4 different carbon/HEPA combination filters. These include the HEPA-SILVER, HEPA-PURE, HEPA-OdorCell, or the HEPA-FreshPlus. While specifications are not available on their website, the primary differences between the SILVER and PURE options are the capabilities in particulate sizes. The PURE is designed to trap larger particles, while the SILVER is designed to filter the smaller particles more effectively.

The OdorCell and FreshPlus filters use activated carbon to filter odors and gases, and from our assumption, the OdorCell comes with a carbon concentration that is higher.

If you decide to use ionization we suggest that you use the unit in rooms that are well-ventilated that are 200 sq ft or bigger. Similar to the Coway make sure you use the unit far away from walls and furniture to prevent soiling caused by the created ozone. Alen promotes that this unit can treat areas as big as 1100 sqft, yet when we use the smoke CADR rating of 300, our recommendation is to not use it for areas that exceed 465 sqft.

3. The Austin Air HealthMate Standard HM-400 – Best Air Purifier for Smoke

This is one of the best-rated purifiers in association with performance.

The filtration process of the HealthMate is superior and close to industrial-grade. It features a 4-stage, mechanical-purification system. It initially stops the larger particles such as dust and pets dander, and then the medium-size particles such as pollen before it passes the air through a 15-pound, zeolite, and activated carbon filter. It then finally removes the smallest of the contaminants with the HEPA filter.

While the company Austin air has made claims that these units are able to handle and indoor space of up to 1500 sq ft, we suggest the unit for rooms that are not bigger than 341 sq ft according to the smoke CADR rating which is 220.

From the perspective of controls, it is really simple. This unit comes with a 4-position, 3-speed control switch found on the front cover. The filter is easy to replace by taking the bottom plate off which features 4 screws, followed by taking out the primary and pre-filter assembly. This purifier sits on caster swivel wheels which really helps when it comes to moving this 45-pound air cleaner around.

4. The Coway AP-1515HH – Best HEPA Air Purifier

The AP-1512HH from Coway does not disappoint. Even though it employs ionization as a step in the filtration process, this unit still performs extremely well. It utilizes a 4-stage process in order to filter the air. It starts with a basic pre-filter which is designed to capture the larger particles, followed by the activated-carbon filter dedicated to odors and gases, which then passes into the HEPA filtration. It then passes the air through the proprietary Coway Vital Ionizer.

If you read over the “How We Choose” section, you will understand our feelings towards air purifiers which use an ionization technique, yet, even so, this unit managed to outperform many other purifiers in association to our detailed testing. We suggest that you use this product in an area that is well-ventilated, bigger than 200 sq ft, as well as far away from furniture and walls which is due to an ozone byproduct that is created.

The Coway AP-1515HH is capable of handling a space of up to 361 sq ft, and it comes with various control features. Some of these include an air-quality indication, self-monitoring, and the Eco mode which will turn off the fans automatically when the pollutants have dipped below the predefined level. It also comes with conventional settings for speed.

5. The Dyson Pure Cool Link – Best Air Purifier for Dust

This is our favorite in association with connectivity and smart features. This unit is partly a fan and partly an air purifier. It features it’s own remote, yet you can also control the unit through the iOS app or the Google Play app. For the users that use the smart-device application, you are able to review reports on air quality indoors and schedule the operation time.

While specifics on the operation are not available on the Dyson website, we have discovered that around 1/15th of airflow through this device is filtered through the activated carbon and HEPA filter which is situated at the bottom of these units. This unit uses a 2-stage filter that first passes the air through a glass HEPA filter, followed by passing it through the activated-carbon layer which offers odor control. The Cool Link comes with 10-speed settings along with the self-monitoring mode which will change the speed according to the air quality that it detects.

We suggest using this unit in areas that do not exceed 200 sqft in order to get the most out of the filtration process. There are 2-flow pattern options that you can choose from using the remote or from a smart-phone app. For the best cleaning, we assume that the “diffused” mode will perform better in comparison to its “personal” mode.

Who Should Invest In An Air Purifier? (Costco | Walmart | Amazon)

Countless people will agree that using an air-purification system indoors has improved their overall health and well-being.

Along with the more common air pollutants such as smoke, mold, dust, and pet dander, there are many other contaminants that you might not be aware of. Every time you cook, treat pests, paint, or use products that contain chemicals, and even printing documents, VOCs (Volatile Organic Compounds) release into the air in your home. The levels of these VOCs will vary from one household to the next, yet the EPA has estimated that the majority of homes contain from 2 to 2000 times more levels when compared to outdoors.

VOCs are very harmful to us, and at specific levels, they can result in throat, nose and eye irritation, nausea, dizziness, and headaches. Exposure to certain VOCs that is prolonged can result in chronic health issues that include cancer and in some cases death.

If you reside in an area that has a lot of outdoor pollution, you let your pets indoors, or you constantly suffer from an allergy or more, or you suffer from headaches, have irritated sinuses and eyes, you can benefit from an air purifier.

Buyer’s Guide: How to Choose the Best Air Purifier? (Costco | Walmart | Amazon)

1. The Filtering Process

We believe there is a significant difference between the purifiers which use a mechanical method in order to filter the air compared to the units that use an electronic method which includes ionization. Ionization might work well for larger areas, yet ozone created as the byproduct from this process becomes a concern in poorly ventilated or small rooms. The ozone particulate is also associated with causing a buildup on furniture or nearby walls.

2. CADR

CADR which stands for Clean Air Delivery Rate is a measure of 100% removal for particles of a specific size from the defined “cubic feet per minute of air”. The testing threshold we use is that a CADR of 200 is the minimum acceptable rate when it comes to smoke. We also went onto calculate the maximum square feet recommended from the CADR. Take note that there are a few variations that have been reported on in a few of the top selections. For example, the Austin Air unit has claimed that their unit can be used acceptably up to 1500 sqft, yet when we used the CADR we discovered that 341 sqft was the threshold.

3. Activated Carbon And HEPA Filters

It is hard to find the air purifiers that do not use the HEPA-rated filters, yet finding the units that use activated carbon filters that exceed over 5 pounds of the medium can become difficult. We definitely gave additional points to the filtration systems that feature 5 pounds or more of activated-carbon.

4. Self-Monitoring

This is a standard feature, that can help you to track the efficiency of the filter. It also uses an alert system which will tell you when you need to replace the filter.

5. Coverage

We will hardly ever look at products before we check on the warranty from a manufacturer. We believe in using a baseline of limited warranties of 5 years. We gave the products that offered improved coverage additional points.

6. Noise

If you plan to use an air purifier in a space like your bedroom, it is best to first find out about the noise that it will generate on the maximum setting. In most cases, the 300 to 400 sqft unit will produce about 55 dB on the maximum setting.
