Even among the best air purification systems available, filtration takes a lot of work. Multiple filters specialize in particular jobs like odor control, killing spores, removing especially tiny particles, and more: most need maintenance or replacement, which can sometimes feel like a juggling act when you just really wanted clean air in a room.
That brings us to Brid, a new venture for a sleek, canister-like air purifier that does several things at once – with a single filter that doesn’t need any maintenance. Is it too good to be true? The secret behind Brid is a set of “nano-structured ceramic filters” that appear to be infused or “baked” with titanium dioxide. This titanium dioxide can apparently react with harmless LED lights and kill spores, viruses, and so on. Periodically wash the filter, and that’s all you need to do.
Those are a lot of claims to make about a new filter, and it’s always a good idea to look carefully at any Kickstarter product featuring suddenly-new technology. Brid may have grabbed a lot of headlines with its promises, but it’s not quite clear how this technology works. What specifically makes bonded titanium dioxide more useful? In what ways does it react with LED lights to avoid the needs of other photocatalytic converters? How does the ceramic filter absorb odors without carbon? Is there an ion exchange process? We don’t know the answers to these questions, because Brid doesn’t talk about it. Warning bells!
Much of the marketing seems to emphasize that the bonded titanium dioxide doesn’t require UV lights or ozone, which the Brid team tells us are bad: While UV light can cause sunburns and you definitely don’t want to inhale corrosive ozone, they aren’t exactly things you need to avoid. No one has ever gotten hurt from a little UVC light in an air filter, and we use ozone particles to help clean pools and clothes.
So we’re left with several dubious claims, some talk about patents with no detail, and a pretty design. Not much to hang your money on, especially when the cheapest option to preorder a filter is still $289.
However, Brid has been funded several times over, so hopefully the product will go to market soon and third party reviews can check out just how well it works in early 2018 (fake Kickstarters have a habit of never actually hitting the shelves, so this is another important test). If Brid really does excel at removing odors from the air and killing living particles, it could make a useful addition to your air filtration system, although it is not designed to help control allergies.
