What are air purifiers?

Air purifiers are mechanical devices that use a fan mechanism and specialized filters to remove contaminants like pollen and dust from a room naturally and permanently. Commercial air purifiers were first made available to the public in the early 1960s, and have made many changes since then.

Consisting of different types of filtering processes over the years, many modern air purifiers come equipped with a load of dynamic capabilities, making them invaluable to many households in America today. Some of the latest functions include, high volume — air moving — fan power, HEPA and Carbon filtration options and onboard infrared pollution sensors, to name a few. Many of the newest portable air purifiers feature all of these great capabilities in one device, and can filter out some of the smallest particles that contribute to allergen-triggers like mold and bacteria.

  • Fan power efficiency
  • Carbon filtration options
  • HEPA filtration options
  • Pollution sensing options
  • Can eliminate very small particles

How do air purifiers work?

There are basically two types of air purifiers: active and passive


Active air purifying units release negatively charged ions into the air, causing particles to stick to surfaces as well as other contaminants. These particulates are then collected through a charcoal-filter in the device, or swept and cleaned up throughout the room. “Active” air purifiers are commonly used to eliminate odors.


Passive air purifiers use air filtration technology to remove pollutants directly from the air through a fan-powered circulation process. Since passive air purifiers permanently remove dust and particulates from the air, many industry leaders recommend “passive” devices over active ones.


The most common type of filters, for passive air purifier systems, are called high energy particulate air filters (HEPA). Some of the more advanced HEPA filters can come with antimicrobial deterrent technologies to kill live pathogens inside the unit. Among the different levels of HEPA available today, H13 filters are considered to be the best for filtering out particles less than .03 microns. The air purifier companies that offer H13 filters claim they are the best for bacteria, tobacco smoke and chemical elimination.

  • Two types of air purifiers (active and passive)
  • Passive types are better
  • HEPA stands for High Energy Particulate Air filters
  • HEPA filters can have antimicrobial capabilities
  • H13 HEPA filters are the best

HEPA comparison

A good TrueHEPA filter can eliminate the air from particles down to .03 microns in size. The H13 HEPA can filter out even finer particles (less than .03) that may be found in bacteria, tobacco smoke and chemicals.

What are the best air purifiers to fight bacteria?

A step up from “True HEPA” capabilities, the Medify MA-25 uses dual H13 air intake filter technology to eliminate particles less than .03 microns – very quickly. This is the latest product release in the Medify catalogue and it can filter out a 500 square foot room in 30 minutes or less; which Medify touts as the highest performance table-table air purifier on the market.

By simply understanding airflow rating, HEPA filtration standards, common pricing and quality ratings you will be ready to make your next air purifier purchase with confidence.

When it Comes to Buying a New Air Purifier

  • Get a purifier that can handle the size of room you want to filter.

Understanding the CFM, cubic feet per minute, from your manufacturer can help you determine the correct purifier for your home or workspace. So, if you have a room that is 100 square feet in size, a CFM rating of the “100” or better will be right for you. Just be sure to understand some of the marketing concepts of CFM based on efficiency. These numbers are usually based on 100% efficiency. A high CFM will work well with the high grade H13 HEPA technology.

  • Get a HEPA or H13 HEPA air purifier.

H13 HEPA, High-Efficiency Particulate Air filtration has the best ability to filter out very small particles down to even 0.1 microns. Now there can be some loss of airflow at that level of filtration. But when it comes to defending against mold and bacteria, an H13 HEPA is the best filter technology on the public market today.

  • You don’t really have to pay a lot for really great air purifiers.

There are some companies out there that charge a huge amount of money for their air purifiers. And most of the time you can expect they have been in the business for a long time, and have established their name in this industry. But, with the many advancements in this technology and the proliferation of new companies, you really shouldn’t have to pay more than $500 for any sized portable air purifier on the market nowadays.

What are some other benefits of air purifiers?

There are a number of benefits from having an air purifier. Besides filtering out large particles like hair, dust or debris, air purifiers can eliminate particles from pets, animals, and both indoor and outdoor pollen. Many people who suffer from allergies and asthma also find benefits with the improved air circulation from air purifiers.

  • Removes dust and allergies
  • Improves circulation and removes dust particles
  • Eliminates allergens that cause pet fall and odor
  • Removes pollens introduced by indoor and outdoor plants
