Pros and Cons of Medify MA-40 Air Purifier
Anatomy of Medify MA-40 Air Purifier
The Medify MA-40 is a good looking device. The front side has a big air outlet that pushes out the air after cleaning it.
The rear side has an inlet for sucking in air and a handle for carrying it around. This air inlet comes with a detachable cover for quick and easy installation of filters. As all the three filters come in a single whole so it is very simple and easy to change them.
The top comprises entirely of tempered glass. All the controls are given here in a capacitive touchscreen. The tempered glass is scratch-less and thermally processed to increase its strength. It is extremely simple to operate this device using the control panel touchscreen. It has the timer, child lock, speed, power switch, the anion controller button, etc. The timer has four different modes; 1hour, 2hours, 4hours, and 8hours. It gives you the option of three adjustable manual fan speeds, but there is no automatic mode. It is flat on either side and has four tabs to stand on.
The Medify MA40 uses the back-to-front air-in, air-out mechanism. It simply means that the air is pulled through the back and then goes through a filtration process that comprises the following steps;
Pre-filtration: Here the air is cleansed of all the big air pollutants like fiber, hair, pet fur, etc.
A preliminary screen does this job.
True HEPA H13 filtration: HEPA refers to High-Efficiency Particulate Air. The HEPA compliant devices can capture 99.95% of air pollutants that are 0.2 microns small. Your hair is around 80-100 microns. So, that makes most PM10 and PM2.5 microns microscopic. But wait, your Medify MA40 air purifier is embedded with true HEPA technology. What exactly true mean here? A true HEPA can get rid of 99.97% of air pollutants that are as small as 0.3 microns. The 13 in H13 stands for the efficiency of the filtration. Its maximum rating is 14 so your Medify M40 air purifier is closer to the highest ranking of filtration. A HEPA H13 will let only 0.05% of air pollutants to pass through in 1 liter of air.
Activated Charcoal: This filter removes bad odor prevalent in the air like the unwanted kitchen smells, pet odor, cigarette smoke, formaldehyde, etc.
Ion generator: This is the last stage of the purification process. It traps bacteria in the air by releasing negatively charged ions. You can turn this off if you are asthmatic or worried about creating ozone.
The immediate attention of MA-40 is that it differs from the air purifier in appearance, which is its advantage. It has a stylish, modern design and is suitable for most aesthetics. The compact form factor also means that it can be placed discretely in the corner of any room without attracting attention. But don’t let its small size fool you, this air filter can cover an impressive 800 square feet of space.
The Medify Air MA40 uses four levels of filtration to catch and remove allergens, pet dander, and more. Pre-filter removes hair, fibers, and large particles like dander. The high-efficiency H13 TRUE HEPA filter is tested to removed 99.97% of particles down to 0.1 microns. This medical-grade filter easily catches pollen, dust mites, and other tiny airborne particles you can’t see. Substantial carbon filter with carbon pellets remove toxic odors, smoke, and formaldehyde. The optional anion generator produces negative ions to charge particles and trap them inside the unit and give your air a fresh feel. It can be turned on/off. All three filters are housed in one filter element to simplify replacement and reliable hermetic sealing.
Air Quality Indicator
If you want to test whether this air purifier is really working, you can refer to the air quality indicator available on it. A small light is attached to the air purifier, and it will display different colors according to the air quality. After using the air purifier for a while, you will see that the air quality has improved and it will be visible in the LED indicator.
The air quality sensor monitors the quality of the air and accordingly adjusts the speed of the fan. It also indicates the air quality in the form of LED lights. If the air quality is very bad the light will turn red. If it is moderately good, then it will turn green and in case all is well it will turn blue.
Built-in Particle Sensor
Not all particles are too large to be captured by the air purifier, so the device has a dedicated particle sensor. You can rest assured that this air purifier will capture the smallest particles, so your house will maintain non-toxic air. If you don’t want to use it, you can turn it off at any time.
If you don’t want the air purifier to run all day, you can choose a timer according to your needs. You can choose a 1-hour, 2-hour or 3-hour timer according to your needs, and the air purifier is only valid for the selected time range. As a result, you can save a lot of energy and at the same time extend the life of the purifier.
The performance of an air purifier is usually gauged by the CADR and ACH. CADR is the Clean Air Delivery Rate. It means how quickly an air purifier can clean an area from pollutants. ACH refers to the Air Changer Per Hour. It means how many times in an hour the purifier will change the room in the specified area.
The company claims that this model has a CADR of 330 and an ACH rating of 2X. it can effectively cover a room of 800 square feet in 30 minutes and a larger room of 1300 square feet in an hour. It is a lofty claim, and our tests reveal it does not quite meet that claim. However, it does come very close to that. In one hour, it can clean a room measuring 1237 square feet. So, it is a very good performance for its size.
The Medify MA40 Air Purifier is not a very quiet model. At its maximum speed, its noise level was recorded as 66dB and at the lowest, it was recorded as 50dB. The noise level is understandable for a motor that powerful. For comparison sake, the noise level of an AC is 60dB while for a refrigerator it is 50dB.
This model has a power rating of 68W. It is somewhat higher than what is prevalent in its category but it will not cause a major hike in your power bills.
Other convenience features included in this model include the facility of child lock, timer (to schedule time off for 1,2,4, or 8 hours) night mode (to regulate the speed to the lowest), etc. The device is also covered by a full lifetime warranty with service by the company. To avail this facility, always use the company specified replacement filters and keep changing them after the recommended time.

Medify Air Purifier Buying Guide
What Is An Air Purifier?
An air purifier is a device that cleans the indoor air of pollutants, allergens, and contaminants. It ensures that the air you are breathing in is pure, fresh, and healthy. If you are prone to allergies or are already suffering from one, or there are asthmatics living with you, or elderly people or kids in your house then you should consider buying one.
How Does Medify Air Purifier Work?
Medify air purifier has a simple working mechanism. It has internal fans that pull in the air of the room and circulates it back after purifying it. There are filters installed in it that removes harmful bacteria, pollens, allergens, dust particles, and other impurities from it.
Why Should You Buy Medify Air Purifier?
If you want to know why someone is urged to have a Medify air purifier at home, you may want to know who these people are and who are doing the urging. Well, the fact is, urge a considerable number of people to own an air purifier. These people may be those who keep pets or smoke indoors.
It is said that pet and cigarette smoke can cause the formation of unhealthy air particles, and it has been actually proved in many studies. With Medify air purifier, these particles will be completely eliminated or reduced.
In addition to those houses with pets or smokers, it is also recommended that those with allergies pick Medify air purifiers for their houses. Medify air purifiers can eliminate common dust particles, which is a common cause of allergies. As mentioned earlier, Medify air purifiers are also recommended for people with pets. In addition to keeping home air clean, Medify air purifiers may also help reduce allergic reactions to pets or pet hair.
How To Choose The Best Air Purifier?
Like most other household appliances, air purifiers are a long-term investment. Therefore, you do not want to make a bad decision about the air purifier you want to buy. This is the main consideration before settling a specific air purifier.
Choose an air purifier according to your preferences and needs. Such as:
- The indoor smoke and dust pollution is heavy, you can choose the air purifier with better dust removal effect.
- The indoor decoration or the purchase of new furniture has serious pollution of formaldehyde and toluene. You can choose a purifier with the function of removing decoration pollution.
- Indoor air is not circulating, air is dirty: indoor air is not circulating, bacteria and dust mites are very breeding, you should choose an air purifier with functions of sterilization, disinfection and allergen removal.
- The area of the house and the room are large. An air purifier with a large amount of air purifying per unit should be selected
Air purifiers also come with additional costs such as filter replacement. Purifier filters can be roughly divided into the following categories: formaldehyde filters, activated carbon filters, HEPA filters, composite multi-function filters, and the service life of various filters Different, the price will be different. Some filters can last for as long as a year while others require replacement every 3 to 6 months. Considering air purifiers ill-perform while using worn out or dirty filters, this becomes a major consideration during purchase.
Types of Air Purifiers
Air purifiers use multiple technologies to deal with indoor pollution. Some work better than others. Some may actually be harmful to your health.
Mechanical filter. This is the type we tested. Air purifiers with pleated filters use fans to force the air through a dense fine fiber web to capture particles. The HEPA filter has a fine filter screen and is a certified HEPA filter that can collect soot and paint pigments of a certain size (for example, 0.3 microns in diameter), accounting for 99.97%. HEPA filters can also remove larger particles, including dust, pollen and some mold spores suspended in the air. (Please note that some filters labeled “HEPA type” or “HEPA-like” have not been certified to meet the requirements of real HEPA filters, but may still perform well in our tests.
As for limitations, mechanical filters do not contribute to gas or odor. And their maintenance costs can be high. Mechanical filters need to be replaced every 6 to 12 months; the price of each filter is up to $ 200, but usually up to $ 80.
Activated carbon filter. The adsorbent filter does not capture particles like a mechanical filter, but uses activated carbon, which can absorb some odor-causing molecules from the air. They can also handle certain gases, but they do not work well with formaldehyde, ammonia or nitrogen oxides. Since they do not fight against particles, many air purifiers will include both activated carbon filters and pleated filters to capture particles. However, activated carbon saturates faster than pleated filters and needs to be replaced more frequently-every three months, while pleated filters are replaced every six to twelve months. And be prepared: the cost of activated carbon filters is as high as $ 50.
Ozone generator. These machines produce ozone, and the molecule can react with certain pollutants to change its chemical composition. This may result in dangerous indoor air quality, CR does not recommend doing so. Manufacturers of ozone generators often claim that the device emits a safe level of ozone, but in the past, our tests found that even at low settings, some ozone generators quickly exceeded the US Food and Drug Administration ’s The limit of 0.05 parts per million. In addition, studies reviewed by the EPA have shown that low levels of ozone (the main component of smog) cannot effectively destroy indoor pollutants. Studies have also shown that ozone is associated with decreased lung function and increased risk of throat irritation, cough, chest pain, and inflammation of lung tissue. According to EPA, ozone may also exacerbate asthma, emphysema and bronchitis.
Electronic air purifier. Electrostatic precipitators and ionizers charge particles in the air, so they stick to surfaces on or near the machine board through magnetic-like attraction. CR usually does not test or recommend it because they produce ozone.
Ultraviolet sterilization irradiation (UVGI). Some manufacturers claim that their air purifiers use ultraviolet lamps to kill viruses, bacteria and fungal spores in the air. But some bacteria and mold spores have the ability to resist ultraviolet radiation. To work properly, ultraviolet light must be strong enough, and the exposure must last long enough-a few minutes to a few hours, instead of the few seconds typical of most portable UVGI air purifiers-to be effective. Although some of the mechanical air purifiers we tested may be functional, CR has not tested UVGI technology.
Air Purifiers And Humidifiers – Which is useful to whom?
Asthmatic individuals: Both devices are great for an asthma patient, but air purifiers are a better option because they remove allergens and other contaminants from the air. Humidifiers make the atmosphere pleasant to breathe.
Babies: Both devices are helpful for babies. An air purifier provides contaminant-free air to breathe while the humidifier moisturizes the air with the correct temperature during hot and cold seasons. Babies will be comfortable.
Allergic people: Air purifiers would be better options because they are designed to eliminate contaminants from the air and prevents the allergens from getting in your lungs or eyes. Humidifiers are not intended to filter the air.
