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.
