Except if you’re new to the world of allergy air purifiers, then Germ Guardian is a name you must be familiar with. The company is one of the frontrunners when it comes to the manufacturing of high-quality air purifiers and their incredible expertise is on display again here. Even though the Germ Guardian AC4825 Air Purifier is not ideal for everyone due to its small coverage area, its sheer quality is obvious for everyone to see.

Equipped with a HEPA filter, this machine is capable of capturing 99.97 percent of the household allergens and dust.  Apart from that, it also purifies the air from nasty odors. In fact, it also kills mold spores, germs, viruses, and bacteria, thanks to the built-in UV-C light technology which works with Titanium Dioxide. The machine also helps to reduce volatile organic compounds in the atmosphere, making it a perfect choice for allergy sufferers.

In terms of capacity, this unit is only capable of purifying up to 167 square feet, which is quite small if we’re being honest. It, however, offers three fan speeds to choose from, which gives you some control over its operation. Meanwhile, it’s important to note that there is an annoying initial smell that comes with the purifier. Of course, it will fade after a couple of uses, but it’s very strong and unpleasant while it lasts.

Pros
  • Equipped with a HEPA filter
  • Removes 99.97 percent of pollutants from the air
  • Three fan speeds
  • Gets rid of unpleasant odors from the air
Cons
  • Small coverage area
  • Has an unpleasant initial smell

  • Coverage area: up to 140 sq. ft.

Compactness and affordability don’t necessarily compromise quality, and the Hamilton Beach TrueAir Air Purifier perfectly demonstrates that. Despite being our Budget Pick, this unit comes with HEPA filters that are capable of removing up to 99 percent of airborne pollutants in a 140-square-foot room. Besides, this allergen air purifier has an airflow of 67 CPM, which is impressive given the compact nature of the unit. On top of that, this device also uses a one-stage filtration process that passes indoor air through the HEPA filter.

Another thing that a lot of people will like is that there’s no need to replace the filter ever. You will, however, have to vacuum the filter periodically to maintain optimal cleaning performance. The HEPA filter is made to catch include pet dander, dust mites, and mold spores, among others up to three microns in size. If we consider the affordable price of this unit, it shouldn’t be surprising that it hardly features any extra features. However, despite not coming with all the bells and whistles, it does what it’s designed to do well and effectively.

Another thing we must not forget to mention is the quiet operation of this machine. Noise isn’t a concern on this unit. If you are sensitive to noise, then use it on “Whisper Clean.” It makes no noise, but still puts out a decent amount of air. Of course, it’s not without its flaws, the first of which is the fact that the fan is placed inconveniently on the side. This means that it may blow the unfiltered air away before being drawn by the machine for cleaning. Also, the unit covers just 140 square feet, which is small.

Pros
  • Affordable price
  • Compact and lightweight
  • Quiet operation
  • Excellent air-cleaning performance
  • Has an airflow of 67 CPM
  • Equipped with effective HEPA filters
Cons
  • Small coverage area
  • The fan is inconveniently placed

Babies are known to have a weak immune system, which is why you need to ensure that their nursery is always clean. If you have a baby room you want to purify, then you might want to consider the Vornadobaby Purio Air Purifier. Equipped with activated carbon filters, this air purifier is capable of absorbing all the odors in your baby’s room. Not only that, but it also features a HEPA filter, which helps to filter 99.97 percent airborne allergens such as pollen and mold from the air.

  • Compact design
  • Gets rid of odors
  • Multiple fan speeds
  • Comes with a useful sleepy time setting
  • Removes 99.97 percent of allergens

Buying Guide

How can an air purifier help with your allergy?

While allergies usually don’t have a cure, they usually can be prevented. One of the most recommended methods of preventing allergies is using the best air purifier for allergies.

Features to consider while choosing an air purifier for allergies

6 Most Effective Air Purifiers for Allergies — Reviews and Buying GuideWhile there’re many things you have to do in the build up to your shopping for the ideal air purifier for your allergy, probably the most important of them all is considering some important factors. Some of those factors include:

Type of filters

Generally, you will want to find an air purifier that utilizes a true HEPA filter. Professional groups and government agencies, which include the American Lung Association and the EPA, recommend these filters as the ideal for air purification. True HEPA filters are capable of trapping 99.97 percent of particles that are 0.3 microns at least in size.

Some air purifiers are equipped with HEPA-type filters, which work in a similar way but aren’t believed to perform as high. Meanwhile, our Editor’s Choice, the Medify MA-40 Air Purifier uses Medical Grade H13 Filters, which is in some quarters believed to be better than true HEPA filters.

Also, your air purifier is likely to come outfitted with a pre-filter that captures the big stuff such as human hair and pet fur before it gets to the primary filter. Some air purifiers come with extra filters such as charcoal or carbon filter, which capture gases, odor compounds or VOCs.

Coverage area

As you might have thought, the coverage area is the amount of space that your air purifier is capable of cleaning without getting overloaded. In the event that you want to save some money, then it’s reasonable to measure the space you want to purify and buy a model accordingly. That’s because the larger the coverage area, the costlier it will be.

However, if the cost isn’t a problem, then it’ll be more reasonable to buy an air purifier that is capable of covering more area than you actually need. With that, you will have a guarantee that the machine you select will be capable of handling your area without any problem.

CADR

Also known as the Clean Air Delivery rate, CADR is a number that allows users to understand the effectiveness of their device in a particular room size. Therefore, the higher the CADR number, the more particles your purifier is capable of removing, and the larger the area it’s capable of cleaning. Some air purifiers have different CADR ratings for dust, pollen, (the largest particle) and for smoke (the smallest particle).

However, bear in mind that not every model is tested with the CADR rating system, real-life reviews and feedback can provide you with an idea of the effectiveness of a device if a rating is unavailable.

Fan speeds/settings

Apart from the filter, there are other things that affect the performance of an air purifier. One of those things are the number of fan speeds. If you’re looking for a purifier that will perform based on the current quality of air in your room, find a model with multiple fan speeds. With that, you will be able to easily adjust the machine’s fan according to the quality of air in your room at a certain period. Boasting ten fan speeds, the Dyson TP04 Air Purifier is the best in this regard.

Noise level

6 Most Effective Air Purifiers for Allergies — Reviews and Buying GuideWhile the human’s average whisper rates at about 30 decibels, torrential rain clocks about 50 decibels. Meanwhile, traditional vacuum cleaners come in at about 70 to 80 decibels. As you might have guessed, the reasons why we are giving this information is that you have to consider the noise level with which you can sleep peacefully.

If you are the kind of person that can sleep in any kind of environment, regardless of the noise level, then this consideration might be deemed useless. However, if you can’t fall asleep when there’s too much noise, opt for an air purify that is quiet in its operation. Some quiet models on our list are the Levoit LV-H13 Air Purifier, the Vornadobaby Purio Air Purifier, and the Hamilton Beach TrueAir Air Purifier.

Filter change indicator

Another important consideration you need to think about is a filter change indicator. As you might have guessed, this indicator will warn you when your filter is due for cleaning or a replacement. Because some of the filters usually last for more than a year, it’s easy to forget about cleaning or changing it. This indicator will allow you to know when you need to change it.

Dimensions

It’s also important to know the dimensions of the air purifier you are looking to buy. It will allow you to determine whether your storage space will be able to accommodate the machine.

Also, the size will determine how portable the machine will be, making it easier to transport it from one room to the other.

Warranty

There’s no assurance whatsoever that your machine won’t break down eventually. Therefore, if and when that happens, rather than getting rid of it, you might have to check the terms of the warranty that comes with it. Air purifiers are usually machines that last for a long time, so you need to make sure your machine comes with a two-year warranty at least.

Extra features

6 Most Effective Air Purifiers for Allergies — Reviews and Buying GuideWhile some features are must-haves, others are just nice-to-haves. Generally, more expensive models are usually equipped with more features, like dimmable lights, programmable timers, and filter indicator lights. Some even come with a remote control, which in our opinion, makes things easier a lot.

FAQ

Air purifiers are engineered to be utilized for long periods of time. So, thinking that using a purifier for one or two hours is sufficient to clean the air in a medium-sized room is a wrong conception. New particles usually swirl around at all times as pets humans, air-conditioning, open windows, and heating systems, are all responsible for bringing contaminants into a room. So, an air purifier has to be used for an extended period of time before it will be able to fully purify the room.

Another thing is that it usually depends on the brand, type, and model of the purifier, so we advise you to look for a guideline on your manual. Normally, you want to run it for around five to eight hours, since you can easily switch it on again after resting for some time.

There are many models that help with pet allergies, including models with HEPA filters. HEPA filters can help to reduce the issues caused by pet dander and solve the issue of quality indoor air.

There are different kinds of filters with various technologies to catch air contaminants. Some of them include activated carbon to catch dust and get rid of odors, while others use HEPA filters to catch the smallest particles. Each type of filter is beneficial and effective in its own way, therefore, each one comes with a different lifespan. Replaceable filters, averagely, should be replaced every three to six months, depending on usage and filter type.

Our Verdict

It’s not every day you come across an air purifier that will cover 1,300 square feet while still being affordable. Well, you’ve just come across such a model in the Medify MA-40 Air Purifier. Apart from covering the largest space on our list, it also comes with four fan speeds, which gives you complete control over its operation. It’s the best air purifier for allergies that we know.

Moving on in our ranking, the Dyson TP04 Air Purifier and the Levoit LV-H133 Air Purifier come second and third respectively. While the Dyson model is unique because of the ten fan speeds it comes with, the Levoit is remarkable for its super-quiet operation. Of course, both models are also suitable for large rooms, which adds to their versatility.
