You may don’t know much about the manufacturer named MamieMac Inc, but the Biota Bot air purifiers are one of the most well-recognized devices on Amazon, especially the recommended Biota Bot MM208. Though the age of this American brand was only since 2016, they have been positioning the firm place in North America market. And talking about the most popular air purifier of this brand, we can’t ignore the Biota Bot MM208. So, let’s take a look at the Biota Bot MM208 Review.

Biota Bot MM208 Price

The Biota Bot MM208 exemplifies the strange place this small brand finds themselves in right now. It’s a desirable and capable almost-flagship air purifier available at an incredibly competitive mid-range price. And this is exactly the formula of success that has run for nearly decades.

While the Biota Bot MM108 before it offers a decidedly entry-level experience, which is suitable mostly for the bedroom, the Biota Bot MM208 has a lot in common with the range-topping machines like Winix U450, Levoit LV-H135 or Whirlpool WP500. However, it doesn’t share the same design, the same air filtration process, and that’s a good reason to consider between models.

What’s more, the Biota Bot MM208 is sticking true to their “small-town values”, and MamieMac Inc has made an advanced air purifier just like the Oransi Finn, but with much greater fan power of a console air purifier. With the nature of an American brand, is it all you need to fall for this air purifier?

One thing we can know about the Biota Bot MM208 is its price, which is a strong contender in mid-range segment with $289. Its price tag is only behind the Biota Bot MM608I, but it features the most advanced air filtration system from this company. That’s why we still consider the Biota Bot MM208 as one true flagship of MamieMac Inc.

Apart from the aforementioned air purifiers, the Biota Bot MM208 directly competes against the top dogs of Winix, Sharp or Oransi air purifier brands. They all have great power, attractive design and a well backed-up customer service. So to say, just only the price tag doesn’t make the Biota Bot MM208 the winner in entry-level of mid-range segment, and we need to review other sections as well.

Biota Bot MM208 Design and Size

Head over to the Biota Bot website, you can see the Biota Bot MM208 as their signature product right at the homepage. We can see why Biota Bot would go with such an eye-catching lead, they have great potential in designing attractive air purifiers. However, the Biota Bot MM208 is far less sexy in my opinion, and the body still gives us a feeling of cheap build. The black color, moreover, is not that great as the same color option in the first Biota Bot MM108, and it’s something that defines all of the cut-price for a flagship product.

While the likes of Winix and Sharp are expanding the space for the air intake grill, Biota Bot MM208 is forging a different path. The air flow is still from the both sides of the front panel, but there is so little space for you to even put your hand in. Even the top air outlet is made slimmer, which narrows the depth of this air purifier to only 11 inches.

For a console air purifier with 22 inches in height, the bottom-to-top air flow system concept is the most proper air direction. I always put the Biota Bot MM208 against the wall, and I think the small depth is perfect for this location.

The top control panel, again, is glowing but you can now turn off the display light.

For a more powerful air purifier, the Biota Bot MM208 weighs only 13.5 lbs. It is easy to move it around your home.

Biota Bot MM208 Filters

When things come to the actual performance of one air purifier, people concern mostly about the quality of the air filtration system, as well as what air filter types are being used. Biota Bot MM208 is advertised to have the massive 7-stage air cleaning system, but we can only count 6 stages in total.

  1. Pre-filter – An elementary pre-filter helps you capture the larger particles like dust, hair and pet dander. The filter can be cleaned by vacuum cleaner.
  2. True HEPA filter – Again, we have another True HEPA air purifier with ability to capture microscopic particles like pollen, dust, dust mites, fibers and mold spores. The top efficiency is measured to be 99.97% for any particles with 0.3 microns in size.
  3. Activated Carbon filter – Removes household odors from smoke, cooking, pets and formaldehyde.
  4. Molecular Sieve Adsorption Filter – With the thin granular carbon, the Biota Bot MM208 can improve the performance of adsorption.
  5. UV-C light filter – Kills a variety of germs, mold spores, bacteria and viruses.
  6. Ionizer – The negative ionizer can improve the efficiency of this air purifier by anchoring the allergens inside the mechanical filter. Can be switched on/off.

If only for the quantity of the air filtration stages, the Biota Bot MM208 could be the champion in the mid-range segment, with all possible air filter types at the moment. However, you may asked what makes this air purifier different from the kind of InvisiClean Claro or even SilverOnyx, with a lot less money. Well, we will find it out.

Biota Bot MM208 uses a real elementary pre-filter, exactly like the Levoit LV-PUR131 or even Winix HR900 (however, we can’t compare with the power of double pre-filtration in the Winix air purifier). The pre-filter is a necessary filter to remove larger particles like lint, dust and hair before they can contact with the True HEPA filter, thus this process prolongs the main filter’s life.

The other two physical air filters are the HEPA and Activated Carbon ones. While the True HEPA filter is the original certified HEPA with efficiency of up to 99.97% for removing any particles down to 0.3 microns, the air filter can only last for 6 – 12 months, depending on use. You still need to regularly vacuum the filter for optional performance.

Again, just like the previous Biota Bot MM108, our today Biota Bot MM208 will utilize two layers of carbon filter to enhance the adsorption process, and extend the life of the main Activated Carbon filter. Thanks to that, Biota Bot MM208’s carbon filter can last for up to 6 months, and you can refresh it by placing in the direct sunlight.

The ionizer from Biota Bot MM208 is told to release 10 million ions per second, and its power is at least double the performance from small air purifiers. However, the Biota Bot MM208 is still not certified by the California Air Resources Board (CARB) to meet the safety standard of not releasing too much ozone. Therefore, if you have asthma issues, you should be careful with this function.

The last thing, we should mention the UV-C light filter, which is introduced first and only in the Biota Bot MM208 of this family. UV-C light filter is capable of killing small things like viruses, mold spores and bacteria. The process, again, can emit a little amount of ozone, and you should turn it off to not trigger any asthma issues.

Again, in real-world tests of Breathe Quality, I put the Biota Bot MM208 in a large room of 200 square feet, and let it run in 1 hour. The Biota Bot MM208, as you can see from the chart below, ended up with a high efficiency of 99.93% for trapping any particles down to 0.3 microns.

However, the Biota Bot MM208 is a mid-range air purifier, and you will need to pay $67 for a pack of all filter replacement. It is, however, still more reasonable than the high-quality filter of Levoit LV-H133 or Winix U450.

Biota Bot MM208 Room Coverage

The Biota Bot MM208 doesn’t have any specifications about the room coverage or CADR rating on paper. You need to contact MamieMac Inc to know the answer, and they would suggest you to use it in a room of 430 square feet.

The ACH of Biota Bot MM208 is 2X – 4X. For most time, this air purifier will only exchange the air in your room every 30 minutes.

The CADR of Biota Bot MM208 is 200 cfm in general. The CADR rating is still higher than others in this price range like Sharp FP-F50UW or Oransi OV200, but it is nowhere near the fan power of Whirlpool WP1000 or Winix U450.

Biota Bot MM208 Sound

The console air purifiers from Biota Bot are not suggested for bedrooms, and you can easily point out the culprit, it is quite noisy at the highest setting. The slim Biota Bot MM208, despite of its size, reach the noise level as high as 60 decibels (db), which matches even the bigger model – Biota Bot MM608I.

This is also the most agreed negative review on Amazon for this air purifier, and you will need the Smart Sensor to keep it running on low speed, and reduce the noise level to only 30 decibels.

Biota Bot MM208 Power Consumption

An air purifier is designed to run for a long time to be more efficient, making the high-priority question in Breathe Quality is: “Do air purifiers use a lot of energy?” To know the answer, we will need to check the power consumption of this air purifier.

I don’t find the part of power consumption to be a strength of one console air purifier, especially if it has the UV bulb as an additional filter. The Biota Bot MM208 is measured to be as high as 70 watts, which is about 3 times the power consumption of Rabbit Air BioGS 2.0.

If you run the Biota Bot MM208 for about 8 hours each day, you need to pay $25 each year.

Biota Bot MM208 Additional Features

We all love the Biota Bot air purifiers for its rich features. However, it can be a good selling point for a budget device like Biota Bot MM108. The mid-range device, like Biota Bot MM208, we won’t be surprised to see such thing like Smart Sensor in it.

Well, the Smart Sensor is the specially necessary feature of one air purifier, as it can help you operate the machine in a smart way. The air sensor can detect the slightest changes in indoor air quality, and through the Auto Mode, Biota Bot MM208 will respond with the automatically fan speed change. As the result, the Biota Bot MM208 will mostly run on lowest speed, and reduce both the noise and power consumption.

The Sleep Mode is also available in this air purifier, running this mode will enable the device at the lowest setting, to guarantee the lowest noise level for a silent night.

Finally, Biota Bot MM208 still has a basic Timer to help schedule the time off. Again, for unknown reason, Biota Bot MM208 doesn’t have the LED indicator for filter replacement, so you should check the filters regularly on your own.

Our verdict

We have quite lots of things to love the Biota Bot MM208. It has great air filtration system, an unique slim design and above all, amazing performance for air purification. The fan power is quite decent, so if you are tight of budget, you should check Winix or Honeywell air purifiers for lower price.

However, the Biota Bot MM208 isn’t really special at the moment, so you should head for other recommendations in Breathe Quality.
