FIWOTTTDA Air Purifier - Review

Installation and Setup

Before starting up the FIWOTTTDA air purifier for the first time, it is essential to make specific preparations. To begin with, it is necessary to remove the protective coating from the control panel. I recommend everyone to remove this coat because it is a bit thicker, so the touch keys do not respond very well to pressure.

After this, the filter should be removed from the housing, unpack it, the protective packaging should be removed, and after you put the filter back inside the air purifier is ready to work. The last step is to plug the power supply into the FIWOTTTDA air purifier, plug it in, and switch it on.

Please note that placing the air purifier at least 20 inches away from walls or other objects is best and will allow it to work at its best performance.

Design

FIWOTTTDA is an air purifier characterized by its tower shape design. The device is white except for the air outlet, which is grey, and the control panel on top of the device, which is black.

When I unpacked the FIWOTTTDA air purifier, the first thing I noticed is that aesthetically it reminds me very much of the Xiaomi Mi 3H, and the dimensions are also very similar.

FIWOTTTDA Air Purifier - Aesthetics

The FIWOTTTDA is a device of not high quality, and the plastic is also not high quality. Although the quality of the plastic is not very important for this kind of device, I have to say that I am a bit disappointed and that I expected the FIWOTTTDA to have better quality.

Although it looks very bulky at first, the FIWOTTTDA is a very light device. The downside is that there is no carrying handle, but carrying it from place to place is not a problem due to the device’s lightweight.

As far as the design of the devices is concerned, I think the engineers could have tried a little harder to make a fan better; sometimes, there is a weird sound coming from it. To prevent the fan from knocking, I recommend that you always keep the air purifier on a hard surface, never on a carpet or other soft surfaces.

Overall I fancy the aesthetics of the FIWOTTTDA air purifier, which is somehow sleek and modern.

Control Panel

The control panel is located at the top of the device, is round in shape, and contains touch buttons and all the necessary indicators that FIWOTTTDA has.

The buttons on the control panel are touch-sensitive. The control panel has the power button, the fan speed button, the timer button, PM2.5 indicators, a sleep mode icon, an auto mode icon, a current fan speed indicator, etc.

FIWOTTTDA Air Purifier - Control Panel

I do not like the fact that the touch buttons are sometimes not sensitive enough, and it is as if you have to find the angle at which the button responds best to pressure. It can be tedious at times, but you get used to it.

All in all, the indicators on the control panel are very legible and visible, the position of the buttons is good, and everything is in the right place. By the way, I prefer it when the buttons are on the top of the device, rather than, say, on the side, as is the case with the Afloia Mage air purifier. Because when the buttons are on the side, they are hardly accessible and not at all practical.

FIWOTTTDA does not remember the last settings, so the device will start in automatic mode every time you switch it on.

Airflow

FIWOTTTDA is, as I mentioned before, a tower air purifier. Almost two-thirds of the device is taken up by the filter, which is located on the underside.

The device has holes at the front and rear through which air enters. The air that is sucked in through the holes is then filtered and exits through the grilles on the upper side of the device.

Size and Dimensions

The air purifier weighs 3,6 kg. The dimensions of the device are 10 x 10 x 20 inches. FIWOTTTDA is a very lightweight device, even much more than you expect when you first see the device.

What is in the box?

You get a FIWOTTTDA air purifier, power cord, True HEPA filter, and user manual when you buy the device. I advise you to be sure to read the explanation I wrote at the beginning of the review to prepare the device for the first start-up. Especially since many first-time users simply skip some essential steps.

Features

In terms of options and accessories, the FIWOTTTDA has a lot to offer.

The multitude of advanced options, some of which are often unavailable on slightly more expensive models, is just a testament to how much FIWOTTTDA wants to be a serious brand with serious air purifiers on offer.

FIWOTTTDA Air Purifier - Design

Below I will describe how FIWOTTTDA’s options work, whether they are all functional enough and whether they could be improved.

Air Quality Sensor and Automatic Mode

The air quality sensor is a feature that is increasingly an integral part of many air purifiers on the market. This is because there is too much competition in the market, and manufacturers have to look for different ways to meet customer needs and how to “force” a potential customer to buy their product.

The imposition of these accessories often leads to a situation, for example, in the case of the FIWOTTTDA air purifier, where the air quality sensor is of inferior quality and does not give entirely accurate measurements.

This sensor basically measures the air particles and displays the amount of PM2.5 in real-time on display on the control panel. However, these measurements often deviate and are not accurate, especially when comparing the readings with professional air quality equipment.

FIWOTTTDA Air Purifier - Front Side

In addition to working in combination with the PM2.5 indicator, the air quality sensor also works in automatic mode. When the device is switched to automatic mode, the device’s speed will be automatically determined based on the air quality sensor readings. Depending on the current air quality, you can see what color the air quality indicator will light up in the table below. 

When it comes to the automatic mode, if the amount of PM2.5 is between 0 – 12 µg/m3, the device will switch to Speed Mode 1, if the amount of PM2.5 is between 12.1 – 35 µg/m3, the device will switch to Speed Mode 3. If the amount of PM2.5 is greater than 35.1 µg/m3, the device will switch to Speed Mode 5.

Given the not too high accuracy of the air quality sensor, I recommend operating the air purifier mostly manually and not relying on the automatic mode.

UV-C Light

UV-C light is an additional level of filtration that can be switched on or off as desired. Pressing the timer button for 5 s turns the UV-C light on or off.

The UV-C light in the FIWOTTTDA air purifier operates in the range between 260-275nm, which is in the field of ultraviolet light labeled as safe. This means that the UV-C in this model does not produce unacceptable amounts of ozone.

Filter Replacement Indicator

FIWOTTTDA uses a filter replacement indicator to let you know when it is time to change the filter. If it is time to change the filter, the indicator will light blue. How long the filter will last depends on several factors, but mainly on how the unit is maintained and the pollution level of the air purifier’s environment.

Timer

One drawback is that FIWOTTTDA does not have a smart app or some similar advanced options, but there is a handy and flexible timer option.

The timer is used to set how long the device should be working. The timer on the FIWOTTTDA air purifier can be set between 1h and 24h.

Sleep

The FIWOTTTDA uses sleep mode, which is a great compliment. Although it is generally a very loud air purifier, the FIWOTTTDA is in sleep mode more than quiet.

When you switch to sleep mode, it takes 3 seconds for all the indicators to go out, except for the sleep mode indicator and the power button, whose illumination is reduced by half. In sleep mode, each second button press will turn on the indicators (wake the device), but only the next press will register the desired change.

Child lock

A great option if you need to lock all the options on the air purifier and prevent accidental button presses. The child lock is activated by holding your finger on the Fan Speed button for 5 seconds.

Once the child lock has been activated, you will not be able to use any of the buttons on the appliance. Only if you deactivate it again (which is done in the same way as activation) will you return the device to its old settings.

Room Coverage and CADR

FIWOTTTDA is an air purifier with a CADR of 380 m³/h or 224CFM, which is sufficient for the device to purify the air one time in a room of 1540 sq. ft. or four times in a room of 385 sq. ft.

FIWOTTTDA Air Purifier - Air Outlet Grilles

Since it is standard to take the size of a room in which the device can clean the air more than 4 times, it is usually 5 times. I will conclude that the FIWOTTTDA air purifier is best used in rooms up to 385 sq. ft.

The FIWOTTTDA is ideally suited for a living room, kitchen, or other similar medium-sized room.

FIWOTTTDA is an air purifier with a reasonable price. Check out more about it in the video above and see if this affordable price makes sense.

Filtration Technology

The FIWOTTTDA air purifier uses 5-stage filtration. I really like that this air purifier uses UV-C Light as one of the filtering stages. Whenever we mention UV-C Light or an ionizer, it is essential to touch on the subject of ozone production. Fortunately, the FIWOTTTDA is a CARB-certified device, which means that it does not produce illegal amounts of ozone.

FIWOTTTDA Air Purifier - Filter

The filter is round in shape, hollow through the middle, and all stages are grouped in layers.

The pre-filter is the first stage of filtration. Its role is to effectively trap and reduce large allergens, dust, and particles.

The second filtration stage is a HEPA filter of medical-grade H13, which removes 99.97% of airborne particles down to 0.1 microns. Some of the particles that this filter removes are pollen, pet allergens, and dust.

The activated carbon filter is the third level of filtration. FIWOTTTDA uses a granular carbon filter, which is more efficient than fiber-based carbon filters. I must point out, however, that this model did not have an enviable performance during the gas filtration tests.

FIWOTTTDA Replacement Filter

Always buy genuine filters for the best performance. As soon as the filter reset indicator is on, you are ready to change filters. Do it as quickly as possible.

The high-efficiency silver ion filter is the last stage of filtration. Its purpose is to help remove some bacteria and viruses. 

UV-C Light is the last stage of filtration, separate from the primary filter. The UV-C is located inside the device, but it is well-positioned so that no light can get out of the device, so a large amount of air is configured to pass by it, so the efficiency of the UV-C light is very high. This light kills bacteria instead of trapping them like the other filters mentioned. The UV-C light on this model is not very powerful, consuming only about 0.8W, far less than the UV-C light in the GermGuardian AC4285 air purifier.

The FIWOTTTDA has no safety check that the filter cover is tightly closed, but it does have a guard to check that the unit is upright, and if it is not, it will automatically switch off.

How do I change the FIWOTTTDA filter?

Like any air purifier that uses HEPA or similar filters, the FIWOTTTDA requires frequent filter changes. Fortunately, the device uses a filter reminder to let you know when it’s time to change the filter.

Filters generally last up to 6 months or about 1800 hours in total. FIWOTTTDA filters are not washable, so I do not recommend washing or putting the filters in water.

However, I recommend cleaning the pre-filter with a vacuum cleaner at least once a month to keep the machine working well and extend the life of the other filters.

Noise Test

FIWOTTTDA uses an incredible 5 fan speeds and an additional sleep mode. This is to be commended, and I usually prefer air purifiers that can offer several different speeds to work at.

FIWOTTTDA Air Purifier - Noise Test

Even though it has many different speeds, the FIWOTTTDA is still a very loud air purifier, especially at the highest speed. The sleep mode, where the FIWOTTTDA creates a sound of around 40.9 dBA is on par with some of the quietest air purifiers.

But the volume at maximum speed, which is around an incredible 70.9 dBA, is a little too loud. I can say with certainty that I have not yet tried an air purifier that can produce such loud noise at the max speed.

Speed Value (dBA)
Sleep Mode 40.9 dBA
Speed 1 41.9 dBA
Speed 2 45.8 dBA
Speed 3 59.6 dBA
Speed 4 66.2 dBA
Speed 5 70.9 dBA

Although some users complain about the strange and very loud scratching sound of the fan, I have not noticed this, to be honest. A slightly odd motor action and a slight scratching noise can be noticed at certain speeds, but it is nowhere near so irritating and loud as to be annoying.

Performance Tests

I recommend using the FIWOTTTDA air purifier in rooms up to 385 sq. ft. I have tested the device in similar or approximately larger dimensions. The FIWOTTTDA showed promising results in the tests, although not as high as I expected.

FIWOTTTDA Air Purifier - Performance Test

I was particularly disappointed with the FIWOTTTDA’s gas and smoke filtering capabilities. The results were very poor, and the FIWOTTTDA failed to combat and neutralize even a small amount of smoke in the room.

With such a high airflow and high fan speed, I think a slightly higher quality carbon filter is what this device needs to get a better score in the performance test.

I have not tested the FIWOTTTDA air purifier in automatic mode, mainly because I am not satisfied with the accuracy of the air quality sensor, so I do not want to rely on this option.

I recommend setting the air purifier manually and relying as little as possible on the automatic mode for best performance.

320 sq. ft. Room Test

I tested it in the room of 320 sq. ft., which is slightly smaller than the recommended dimensions. I installed a FIWOTTTDA air purifier and left it running at speed 5.

# Starting Baseline After 60min
PM 2.5 102.2 6
PM 10 143 8.4
Particles 148210 8769
AQI 134 8

After 60 minutes of operation, the FIWOTTTDA improved the air quality by about 94%, which is an excellent result that is on par with much more expensive air purifiers.

560 sq. ft. Room Test

However, in the second test in a 560 sq. ft. room, the FIWOTTTDA was not so good; it did slightly worse.

In 60 minutes of operation at maximum speed, this model reduced the AQI from 136 to 20, improving air quality by about 85%.

# Starting Baseline After 60min
PM 2.5 104 14.5
PM 10 145.6 20.3
Particles 150844 21124
AQI 136 20

This is not such a great result, but not too bad when considering that this room is larger than the recommended dimensions.

I recently had the opportunity to test the Alen BreatheSmart FLEX air purifier, which gave much better results in rooms of the same dimensions. If you are interested in the details, I recommend you read the review on the Alen air purifier.

Operating Costs

The FIWOTTTDA is a medium-sized air purifier but with an engine power of only 42W. This is a big surprise and an interesting fact, especially considering that the FIWOTTTDA generates such ample airflow with this engine power.

If you let FIWOTTTDA run at full speed, 24 hours a day, for a month, your electricity bill would increase by about USD 3.95, which is really not much.

Speed Power Usage (W)
Stand-by 0.6W
Sleep Mode 2.7W
Speed 1 3.4W
Speed 2 6.1W
Speed 3 15.3W
Speed 4 27.2W
Speed 5 45.2W

Remember that you will be using the device at maximum speed for the minimum time, so the electricity bill will often be much lower.

In addition to the electricity costs, there are also the costs of replacing the filters, which need to be replaced on average 2 times a year. The price of replacement filters for FIWOTTTDA is much higher than I expected, so the maintenance costs of this air purifier are slightly higher on an annual basis.

FAQ

Can I use the FIWOTTTDA air purifier all day?

Yes, you can use the air purifier 24 hours a day, but remember that this leads to higher consumption and more frequent filter changes on the device.

Does FIWOTTTDA produce ozone?

FIWOTTTDA is a CARB-certified air purifier, which means it does not produce illegal amounts of ozone.

What is the warranty on this model?

FIWOTTTDA provides a 1-year warranty for this model. The owner’s manual extends the warranty for an additional 6 months, but a written online web address is not available.

Pros and Cons

To revise, here are the advantages and disadvantages of the FIWOTTTDA air purifier:

Pros

  • Air quality sensor
  • Automatic mode
  • 5-stage filtration
  • UV-C light
  • Ozone safe
  • 5 fan speeds
  • Sleep mode
  • Very low power consumption

Cons

  • Inferior build quality
  • Not so good performance for smoke
  • Air quality sensor could be a bit more accurate

Final Thoughts

The FIWOTTTDA air purifier is a new model on the market. In the sea of air purifiers that have appeared on the market in recent years, we are increasingly encountering new, unknown air purifiers that are mostly untested. It is challenging to find a valid review.

Therefore, I try to test as many different air purifiers from different brands as possible to make it easier for potential buyers to make the right decision.

Although FIWOTTTDA is a new brand on the market, I have to say that I am delighted with the range of this model. With some shortcomings, which I believe will be corrected in some future models, I think that this brand has a bright future.

FIWOTTTDA is an air purifier that I recommend to users who want a solid air purifier with very high airflow, a large filter, and many options for a reasonable price. On the other hand, I would not recommend it to users who want an air purifier whose primary purpose will be to neutralize smoke odors in the room. Also, it is not recommended for users that like a very accurate air quality sensor and want it to operate in automatic mode without errors.
