A powerful air purifier can filter out workplace indoor airborne pollution and improve the quality of the air you breathe for so many hours each day.

The Medify Desktop Solution

Medify Air is a USA based company with a solid reputation for high quality air purifiers.

The recently released Medify Air MA-18, you can see here on Amazon, is their compact desktop model, particularly well designed for people working in an offices.

At only 8.4 x 11.2 inches and weighing just 5.3 pounds, the MA-18 is light and portable.

Despite this, its powerful 360-degree air intake purifies the air in an entire 400 ft² workspace every twice every hour. For a 200 ft² home office this figure increases to 4 times every hour.

4 air changes an hour is highly recommended for people who suffer from asthma, allergies and airborne chemical sensitivities.

Consider the benefits of the new MA-18 for your office desk if you are asthmatic or susceptible to allergens and other indoor air pollution.

Medical Grade HEPA H13 Filter

MA-18 Medify

Medical-grade H13 True HEPA filters are used in all Medify Air models. These superior filters capture 99.97% of harmful particulate matter, right down to 0.1 microns.

H13 HEPA filters work much better at trapping bacteria and viruses which is why they have a medical-grade rating.

Activated Charcoal for Gases

The MA-18 also has an activated carbon filter to absorb harmful VOCs like benzene, tetrachloroethylene and formaldehyde.

These toxic gases are emitted by office supplies, furniture and flooring and especially electronic equipment like printers and photocopiers.

Negative Ion Generation

An optional ionizer in the MA-18 generates 5 million negative ions per second. These negatively charged ions attach to all kinds of indoor air pollution, making it too heavy to float.

Negative ions also counteract positive ion negative effects, including tiredness, tension, anxiety, irritability, headaches and respiratory problems.
