Tall But Slim

The Medify MA-40 is a tall air purifier with 26 inches in length. It is 11 inches wide which makes it quite easy to be placed in a crowded space. It weighs 15 pounds and this is solid enough to avoid wobbling when children or pets play around it. It is also convenient to lift or move as there’s an integrated handle to help you with that. Guess what, the device has corner feet at the bottom which will prevent it from sliding.

High Airflow Rates

The MA-40 air purifier is known for its excellent performance and in big rooms too, up to 800 sq. ft. In a big room, the rear intake draws in unclean air and releases clean fresh air through the front outlet. In this way, the air in the room circulates twice an hour. 

The device also delivers fresh air at a speed of 330 cubic feet in one minute. This rate is still at the high end of the CADR scale.

Medical-Grade H13 Filter

The Medify MA-40  filter is a 3-in-one filter that helps to trap allergens, get rid of odors as well as other VOCs. This happens without letting air escape between the layers. The filter also has an activated carbon layer, a true HEPA filter layer, and a pre-filtration layer.

The HEPA filter in this particular air purifier is a medical-grade H13 media and has different levels of efficiency. In this way, it traps 99.97% of 0.3-micron as well as 99.95% of 0.1-micron particles. This makes your air very clean in a way that other purifiers don’t do.

Variable-Speed Fan

At one of its 3 speeds, a variable-speed fan can circulate the air in a room. As the user, you can choose your preferred speed and let it be static. 

You can also switch to a dynamic speed when you put the device on auto mode. For quieter sound, you can set the fan to its lowest speed with the sleep mode. It doesn’t matter which model you choose as the device only uses 52 watts of energy. Therefore, you don’t need to worry about your energy bill.

Air Quality Sensor

With the MA-40’s air quality sensor, you’ll be sure that you are breathing in fresh and clean air. This season helps to detect pollutants and particles even up to 2 5-micron widths. 

Once it has detected and measured the volume of such particles in the air, it shows the column on an indicator in front of the screen.

Particle-Grabbing Ionization

Most times,  germs and allergens may be too tiny and invisible. The most efficient air purifier may not even be able to collect it. This is where an ionizer comes in as it helps to collect tiny particles. 

It does this by releasing anions that stick to the tiny particles and make them big enough to be collected into the air purifier’s inlet.

Convenience Features

There are two other convenience features of the MA-40, apart from the auto mode and sleep mode. The first is a timer which helps you save up energy if you don’t want to run your air purifier all day. You can set the timer to your preferred time and once that time is up, it automatically turns off.

The next feature was made for those who have curious children. The kids may want to play with the air purifier while you’re out. 

This feature, which is holding down the lock button prevents the child from changing any settings while you’re out.

Glass-Top Control Panel

How about having an air purifier that’s not susceptible to scratches? The MA-40 has a glass control panel instead of plastic. The panel contains buttons that work with a quick tap and is very easy to use. Whenever you adjust the settings, a soft chime will notify you that the change has been effected.

Lifetime Warranty

All the filters are contained in one cartridge and this makes it very easy to change. You can easily pull off the rear access panel and also remove the filter without soiling your hands.

The filters last for 6 months and the panel has an indicator that helps you know when to check it. As long as you maintain the device as supposed to and change the filters regularly, Medify will incur the costs of necessary repairs and faults.

NOTE – besides the models from this brand Medify, you can find some other cheap air purifier reviews on our website.

Premium Purification

Because of its weight and size, it would have been nice for the Medify MA-40 to come with wheels. Besides that, it has everything that a top-notch air purifier should have. 

Because it is tall yet slim, it saves floor space and has stabilized feet. Its one-piece H13 filter is very easy to use, maintain, and change. The same thing goes for the CADR.

Its 3-speed fan has modes that you can control and the air quality sensor never fails to let you know that you’re breathing clean air. 

Everything about the device is just great, starting from the child lock, timer, and right down to the glass top. Adding the lifetime warranty to the features of the MA-40 is just unbelievable.

Automatic Air Quality Upgrades

Technology, as well as design upgrades, can be gotten from everywhere on this unit:

  • The air quality indicator changes color to show the improvements or the reduction in air quality. Also, the indicator upgrades in real-time, showing color from poor, average, and then to good.
  • If you automatically adjust the fan, it will move at a higher speed when you need it or lower. You can also control the fan and choose if you want it to be low, medium, or high.
  • There’s a readout that shows the PM2.5 air quality in digits. The lower the number, the better the air quality. These numbers show how effective the air purifier has cleaned or purified the air. This helps you to breathe in clean air and maintain healthy lungs.

 Cleans Air Effectively

This particular air purifier has a CADR rating which is 950. This means that the air purifier fan has been tested and proven to efficiently and effectively clean the air in large spaces. Most air purifiers don’t do this.

The Medify MA-112 is the largest air purifier Medify has produced so far and it covers up to 1,227 square feet. It is quite scarce to see air purifiers out there in the market that can compete with how powerful this device is.

The Medify Air MA-112 has four levels of filtration which it uses to collect and eliminate allergens like dust, pet dander, and many more: 

  • The pre-filter eliminates fibers, hair, pet dander, and other large particles.
  • The next level of filtration is the HEPA H13 filter that eliminates 99.97% of tiny particles down to 0.3 microns. It catches tiny particles in the air which you can’t see and makes the air clean for you to breathe. These particles include pollen and dust mites.
  • Then is the carbon filter that had carbon pellets. It helps to get rid of toxic and harmful odors such as smoke.
  • The last is the optional anion generator. It releases negative ions to freshen the air.

 Having filters on both sides makes this air purifier a very good choice. This is because dirty air is pulled in from both sides, moving to the HEPA H13 filter and then to the carbon filter. In essence, more air is pulled in and filtered faster, thereby giving you more fresh and clean air.
