Frequently Asked Questions
The long list of why BRID stand out when compared to others (Tedious read, but explanatory):
"@Ameet Khara we have not had a chance to review Molukule, or other similar products, mainly because our approach is much more technical and our goals also included trying to make consumers save money on the dreaded consumables.
From the information that is publicly available and various spec sheets we're able to list a series of clear advantages that BRID has over most, if not all, similar purifiers (some advantages might be in common with others, but certainly not all):
- BRID uses visible light to achieve the same result as others, therefore it does not produce toxic ozone. I believe all the others use either UV-C or UV-A light. UV-A is better than UV-C, but, as far as we know it still produces small quantities of ozone. BRID plays in a different league here, as our target was to get rid of both UV-A and UV-C. Keep in mind that the honeycomb has been in the works for several years and that the research group is deeply involved in both ceramic and nano particles (The patents explain well how much research is behind it).
- BRID uses a nano ceramic non traditional filter. Our modified TiO2 is baked and bonded to the honeycomb. This is done so that particles cannot escape it. Most, if not all other filters are conventional ones and while we did not test them, we can only assume that TiO2 particles will be airborne right from the moment you turn them on. We believe BRID has a massive advantage over older / traditional filter technology as the honeycomb was thought with the volatility of TiO2 particles in mind. We wanted them bonded forever to the filter right from the start.
- When it comes to pricing, well, obviously BRID is less expensive than competitors, at least during the Kickstarter campaign
- Consumables is one more BRID's massive advantage. Contrary to other similar filters BRID can we washed and re-used over and over again. I believe that competitors today will charge you from $100 / year to several 100s for changing filters. They also become less effective with time (They lose TiO2, while BRID does not). On top of that, changing filter once a year for $100 is a good guess, but is it really how often you should do that? With BRID you can choose to simply clean it as many times you want without spending an extra dime.
- BRID's modular design is unique and can easily adapt to different spaces and needs. It can also be upgraded by changing modules. We put some thought into not having to trash the entire unit and waste a lot of $$$ in case of upgrades. I do not believe any other similar purifier does that. We definitively put some love into it.
- Last, but not least, BRID's honeycomb is covered by several patents (Cited in the campaign), so there's some work to do for others to catch up :)"Last updated:
The principle is the same, but BRID, unlike PCO uses a series of patented processes, such as visible light, opposed to UV Light, used by all the others, which produces toxic ozone in various quantities. BRID is the only commercial purifier that uses Visible Light, therefore not producing ozone at all. BRID is also the only purifier of this kind that uses washable filters (Another patent), making it virtually endless. BRID is also modular and can be scaled and adapted easily. Last but not least, competitors have a staring price ranging from $600 to $800. BRID starts at less than $300, 1/2 the price of the nearest competitor, despite BRID's multiple performance advantages.Last updated:
Brid's effect on specific viruses is still undergoing testing. We will post detailed results as soon as they will be available.Last updated:
BRID will get rid of mold spores that go through the filtration system, therefore it will get rid or drastically reduce common allergy symptoms such as wheezing, rash, watery eyes, runny nose, itchy eyes, etc. BRID's nanoceramic filter will effectively stop spores germination.Last updated:
BRID deal very well with VOCs, as photocatalysis eventually transforms them into VO2 and vapor. VOCs are one of the main reason for pollution in cities (Together with NOx, where Diesel engines are present in large numbers). Here a short list of the main VOCs:
Dichloroethyl ethyl ether
Trimethylpentanediol monoiosobutyrate BHT
Trimethylpentanediol diisobutyrate Caprolactam
Here's is also a NOAA study from 2012:
and some more documentation.
One of VOC's problems is that it generates ozone.
Interestingly BRID is the only PCO Purifier that does not produce ozone, on top, of course, of being able to 'Vaporize' it. Why? Because all PCO purifiers use UV lights and they produce ozone, while BRID's patented technology uses, for the first time, visible light, the only way to avoid ozone production.Last updated:
Organic odors might include smoke, pet urine, bodily fluids, cooking odors, Odors from organic compounds found in general air pollution, wastewater, soil emissions and building emissions.Last updated:
Nope. BRID is calibrated to use up to three power filter modules. If you use 4 or more power filters, BRID just won't work.Last updated:

The short answer is: ABSOLUTELY YES!
What is formaldehyde? CH2O is a chemical widely used by several industries to make, for example, home building products. Aside from ALS risk or other nervous system consequences, formaldehyde is a respiratory irritant that causes chest pain, shortness of breath, coughing, and nose and throat irritation. It can also cause cancer, and has been linked to an increased risk of asthma and allergies in kids.
BRID’s ceramic honeycomb, as test results described below show, is a powerful tool against these risks.
Photocatalytic decomposition of formaldehyde pollutant by ‘BRID’s doped’ ceramic honeycomb, activated with visible LED Light, has been tested to verify the effectiveness of BRID air purifier. Tests have been carried out in controlled conditions by using a flow of formaldehyde through a TiO2 ceramic honeycomb filter box highlighted by four LED light sources (visible light). HPLC has been used as final detector.
Expected results: according to published research (Chemical engineering journal, 218 (2013), 9-18)), formaldehyde should been degraded by the presence of highly reactive radicals 2H+ and Hydroperoxyl produced on the surface of BRID’s activated honeycomb.
Actual results: The chemical mechanism led to the transformation of formaldehyde into hydroxymethylperoxyl radicals which subsequently reacted with Hydroperoxyl giving rise to formic acid as byproduct (plus O2 and water). The presence of positive holes (2H+) is then responsible for the "complete oxidation" of formic acid into carbon dioxide (CO2) as final product of the whole process.
Through this process the transformation of formaldehyde into carbon dioxide has been tested to have an impressive efficiency of 82,7% reduction in one single passage!Last updated:

They are completely different technologies. Photocatalysis (BRID) is very effective, virtually vaporizing NOx, VOC, Carbon Monoxide, Bacteria, Mold Spores, etc.
An HEPA filter just captures some of these organic matter. PCO technology is far more advanced than a simple glorified filter (Essentially HEPA).
Photocatalysis, a well known process for decades, generates free radicals that bond to gases, organic matter, etc. changing the molecular structure or cell membrane and transforming them into vapor or CO2.
Current PCO technology uses UV light, which generates Ozone (Which is toxic). BRID is the first PCO filter that uses LED Visible Light instead of UV. It does not produce any ozone as a byproduct.
BRID also uses patented technology to bond TiO2 nanoparticles (Titanium Dioxide), needed for the oxidization process. Most PCO purifiers use regular filters that cannot contain those particles. The second you turn them on, they are airborne.
Last but not least, BRID’s nano-ceramic filter can be washed and re-used over and over again. 99% of other PCO and HEPA filters have to be changed continuously and their monthly / yearly price can be steep. On top of that BRID is very affordable, especially during the Kickstarter campaign.
BRID has quite a few innovations and is widely more effective compared to HEPA filters. It also has several advantages compared to other PCO filters, which are all very similar one to another. BRID’s patents are a testament to the leap in technology we made. The filter is the result of 13 years of scientific research and it’s exclusively found on BRID (For the time being, at least).Last updated:
We’ve chosen an adequate fan and set of LED lights in order to build the fully working prototypes, but as the campaign is live, we also have another couple of sets of LED light and a few fans lined up for testing before productions starts.
The final choices will be made around the end of September / October and we will target performance / db level and power consumption, this will also be the final certified model. For example, right now the current best candidate
for LED Lights is Würth and we should receive a few sets of LEDs by the end of the month. The final production BRID will also have an app controlling it and we will have such functions as: “Night mode” as well as probably “Low energy Mode” or “Quiet Mode”, etc. This said, the technical choice / achievment of using LED lights for BRID (The only one currently on the market) will probably make it the one consuming less energy, as older technologies are forced to use UV-A and UV-C lightsLast updated:
