This can be an often painstaking procedure taking days to fully evaluate the influence of the air purifier, but such patience certainly pays off in our extensive knowledge of these products. We are extremely confident this guide will be an invaluable resource for you.

What Is a HEPA Filter?

HEPA filters have revolutionized air quality and approaches to tackling allergies. HEPA (high efficiency particulate air) sifts through various pollutants in the air at the particulate level. These include everything, from pollen to mold to dust, as well as smoke removal and pet dander. Through ultra-fine mesh, pollutants are extracted from the air, filtering out the natural, healthy air which will not irritate the lungs and making air cleaner and safer. This is particularly important when considering families and friends with asthma or allergies- HEPA filters eliminate discomfort and bring peace of mind.

Of course, installing such air purifiers is a lifestyle choice- you are choosing to eliminate those pollutants which affect your respiratory system by installing an electronic device in the home. However, as such a constant presence in your living/work space, things like size, amount of noise, and aesthetic appearance are important factors. HEPA air filters/purifiers are designed to be as inconspicuous as possible- quiet, peaceful machines that do their job so you can get on with your life.

How HEPA Filters Can Help and Why You Should Buy One

So why buy a HEPA air filter? Does it really work? What benefits should I expect? What to consider before buying an air purifier? Can my allergies be defeated with it? In fact, these are all important questions and it’s vital for you to know what you will be getting for your money.

The home is your living space and your nest that provides your personal tranquillity. Yet particles which compromise the quality of the air also compromise the quality of relaxation. Moreover, while allergens are typically associated with the outside world, they can easily drift into your home and cause the same discomfort and ailments you might expect outside.The respiratory system is the main area likely to be affected, and problems stemming from this can go as far as cancer and even death. However, HEPA filter air purifiers remove these tiny particles that cause major discomfort and allergies.

A HEPA air purifier is also a lifestyle choice. Once you experience the cleanliness of the air around you, the thought of going back to compromised air quality can seem incomprehensible. Allergens may lurk in the tiniest of crevasses on rugs and couches, bed spreads and worktops. And the trigger point of allergic reactions can come from a range of sources, many of which you may be unaware of. Subtle mold, dust, gas, pollen, etc. are more prominent in any home than many would believe, and smoke removal is surely a necessity. Certainly when considering appliances like cooking fixtures, cars, fireplaces, etc. there are various sites where pollutants may find a home and enter the living space.

But the best HEPA air purifier can rejuvenate any room. When used as part of a commitment to whole cleaning throughout the living space, any health risks or allergies, no matter how major or minor, can be eliminated. Basic cleaning techniques, such as laundry, cleaning surfaces and vacuuming ensure the work of the HEPA system is not in vain.

Mistakes to Avoid When Choosing the Best HEPA Air Purifier for You

With our comprehensive understanding of HEPA air purifiers and our analysis of reviews, we are confident in recommending the best of the HEPA products available. The layman is unlikely to be able to distinguish between effective facets of different purifiers, and we are here to rectify the situation.

The phrase ‘99% effective’ is often lauded around. But is this a figure worth your hard-earned money? Is this a feature marking the best HEPA air purifier?

The generally accepted figure for a top quality HEPA air filter is 99.97%. And while 99% sounds great, it’s likely to miss crucial particulate contents which should be taken very seriously. Therefore, 99% for us is just not good enough, and you should know the same.

The internal mechanisms of the product are also important to think about- the whole system is important. Automatic modular features, air quality sensors, and other facets of the purifier must be considered in relation to your lifestyle and the environment you intend to place the purifier in. For instance, automatic modes are critical if you think you’re unlikely to change the modes yourself. Having to do it manually is often a time-consuming and easy-to-forget task that limits time for other important things. Automatic air purifiers adapt to larger presences of contaminants in the air. This is not only more efficient, but safer, and a comforting advantage over manual systems.

Key Factors and Features to Look For

Filter Class

HEPA filters come in different classes, and it’s important to understand which class will give you the desired effect you seek. The E class has the lowest retention level, at between 85 and 99.5%. From there, differences are minor- H class and U class filters give gradually higher retention levels up to around 99.99995%, as well as specified local retention ranging from 99.7-99.999%. Be sure to be attentive to class and retention level when considering a HEPA air filtration system.

Airflow Design Characteristics

Airflow design is important when considering the overall operation of the system. Higher or lower airflow can influence energy consumption and noise level. In addition to this, the environment may influence airflow resistance, so it is always important to gain a reading on the airflow characteristics of different HEPA air filters and find the one that best accommodates your environment.

Noise Level

Aside from removing pollutants, such as molds, dusts and pollen, noise is another pollution we wish to avoid in the whole home. Noise levels of HEPA air purifiers depend on the speed and level at which the system is running. After thorough analysis, any purifiers with a highest noise level above 55 decibels (normal conversation volume) are not considered. With that being said, purifiers would only be run on high when a wealth of pollutants pervade the space, such as nearby smoke.

Filter Replacement Indicator

Each filter has a time-frame with which it’s designed to be replaced. This can range from a year to 5 years and beyond. When buying, the annual operating cost must be weighed against the consistency of filter replacement required to evaluate the best option moving forward.

How We Picked and Tested

Rowenta PU6010 Intense Review

As experienced air purifier aficionados, we understand the subtle differences between a good air purifier and a great air purifier.

This air purifier is best designed for homes with pets, and works superbly in terms of odor reduction with its 2 carbon zeolite filters, while vacuum clean filters reduce maintenance costs.



Often one of the cagiest points regarding air purifiers, this product comes at a welcoming $40-50. Depending on the urgency of air purifying, this can be an ideal option as a low cost, rewarding experience for smoke removal and other major pollutants and allergens, such as mold and pollen.


One of the best things about this product is it’s odor reduction.

This is achieved by the 2 carbon zeolite filters, which do require replacement.


This product covers 140 square foot rooms. While not a huge area, the focus on pet odors means it is generally designed for targeting more localized regions of air quality, and should be treated as such.


As opposed to the prevailing tendency of these products to require constant filter replacement, this product offers a satisfying vacuum-clean filter, allowing for self-maintenance at a low-cost.

Particulate performance

With it’s emphasis on pet owners, it is relatively efficient at reducing the presence of pet hair and dander, some of the biggest allergens in such an environment.

Coming in at around $100-200, this again hits the middle of the road when considering similar products on the market. With very respectable performance, it is certainly worth the money.


Charcoal filters reduce the effects of odors in the space, as well as the HEPA filter, like others on this list, targeting up to 0.3 micron sized particles. This encompasses pet dander, mold, smoke removal, and other major odor causing substances.


This again works at about average coverage, so smaller and more medium spaces are likely to hold up. Avoid larger rooms where the effects may be minimized.

Large Space Pick


Winix WAC5500 True HEPA Air Cleaner with PlasmaWave Technology

Get It On Amazon

Best for Medium to Large Coverage

The Winix True HEPA Air Cleaner is extremely effective for larger spaces. It has carbon pre-filters and an auto-mode which allows the filter to work harder when needed.



Looking at around $200 for this product, it is not the most expensive on the market but does play to the higher end of the market nonetheless.


The carbon prefilter arrangement is generally the desired route in this respect, and this is present in this product. Even those odors which one becomes ‘nose blind’ to can be eliminated.


The coverage area is extremely effective for medium to large rooms. This makes it a good option for most air purifying situations, and it can certainly reduce the presence of allergens and pollutants if in a ‘normal’ sized room.


With an auto-mode built in, this filter adjusts itself to the environment. Not only does this offer efficiency in terms of energy, but is also a better filtration system for it. This automatic adjustment is one of the biggest pluses- so often we forget about items such as air purifiers and thus maintenance and proper use fall by the wayside.

Particulate performance

We recommend a particulate retention of 99.97%, that offered by the top HEPA filtration systems, and that is exactly what you find in this product.


  • Effective coverage
  • Automatic adjustments
  • Carbon pre-filter controls odor


  • Specific filter required for replacement
  • Relatively expensive
