Welcome to our FAQ's page! Here is where you will find some handy common questions and answers. If there's something not here that you wish to know, simply get in touch at ask@briiv.co.uk or check out our support page


Q. How often should I have briiv on?
A. In terms of how long the briiv should run for or how often you should cycle the air in your room, we would say that naturally depends on the environment you have it in. A space where the atmosphere doesn’t change very often like a bedroom with closed windows and doors, won’t start to become stale and have particulate matter noticeably around until likely the next day, so one 'full pass' a day would probably suffice. If briiv is in the kitchen for example and a couple of meals a day are being made by family members, or you pets running around leaving dander about, then your machine will likely need to run a little more often than once a day.

By a ‘full pass’, we mean that the unit has successfully taken in and cleansed the entire volume of air in the room. We measured in a 6m x 6m room for example, on full power (Level 4) briiv will do this in one hour; and Level 3 in about two hours. Level 2 in about 4 hours; and Level 1 in about 6 hours. So depending on where you have your air purifier and the localised environment, you may need to run it more or less, but we would recommend at least one full pass per day to ensure a more constant higher quality of breathable air.

Q. If I have extra filters how can I store them?
A. For storage of your filters we would recommend simply keeping them in a cool, dry place. In the boxes, the filters will have no problem sticking around for a couple of years harmlessly until you need to come to use them, so there is no need to worry.

Q. What do I do if there is a build up of dust on my moss filter?
A. This is great sign that your moss is doing such a brilliant job of capturing that matter and stopping it from floating around your personal atmosphere. Of course, after a longer period of time, the internal organic construction will start to become full and will need replacing in a couple more months. In the meantime, in terms of how to refresh the moss slightly, you can actually carefully pick the moss out of the glass dome and either outside or over a bin, gently brush over the branches with a tissue or your hand to remove the standing dust, ensuring you wash your hands carefully afterwards, replacing the moss back into the glass dome afterwards.

Q. Are the filters biodegradable?
A. While our filters are compostable, we don’t recommend that you use them as a compost for food you may grow yourself due to any harmful minerals that may still be present in the compound. The compostable nature of the filters means that however you choose to dispose of them, they will not harm the environment.

Q. Does briiv require/contain batteries?
A. briiv does not contain or require any batteries to work. briiv utilises a 5V USB connection to power the unit.

Q. Can briiv be charged via computer/cellphone?
A. briiv runs from 5V USB and can run from mains power, laptops or even a power bank if you wanted to keep wires to a minimum.

Q. How does humidity/temperature/amount of CO2 in the air affect its performance (assuming, say, a gathering of 7 people)?
A. None of these will affect briiv’s performance as it’s just capturing those harmful VOC’s and particles in the air. It will not reduce the CO2 level in the room as that’s a whole different filtration approach. However, in a normal dwelling that is not sealed off (like an aircraft), CO2 build-up is not normally an issue.

Q. Does my moss filter need to be watered, fed or washed?
A. It is highly not recommended to let the moss come into contact with the water, because this will start the composting process of the moss. Before the reindeer moss is packed up and sent out, it is treated with a natural glycerol, which helps it retain its vibrancy and springiness, water will break down this coating and the moss will become brittle.

Q. What is your definition of "improve the air quality"? What measurements does that entail?
A. So this is the time it would take to fully cycle the air of the room through the filter in line with standard Clean Air Delivery Rate (CADR) tests. We’ve said ‘improve the air quality’ because this is the fairest way to describe it as every room will vary in the particulate count and we did not want to make a false claim that some others make. The improvement will be dependent on how high the initial room pollution is, so if the room starts off with a very high particulate count in the unhealthy 150/100 ug/m3 count, for example, the reduction will be a lot more than a room that already has a very low particulate count of, for example, 2.5 ug/m3. Briiv delivers approximately 53 cubic feet per min of purified clean air at its maximum setting.  

Q. How efficient is it if there's air circulation in the room due to windows or air currents?
A. Air currents generated by another fan or people moving around are beneficial to the filtration efficiency, but, as with all air filters, it’s not recommended you use briiv whilst windows are open as you will in essence be trying to clean the outside air, which briiv would do but I think you’d agree this is a big task.

Q. Does briiv use an Ionizer or generate Ozone?
A. briiv doesn’t use an ionizer and doesn’t generate ozone.

Q. How loud is briiv?
A. briiv is rated at around 45dB (on speed 2), the equivalent of a quiet office.

Q. How do I clean my briiv?
A. If you need to clean your briiv, unplug it from the power source and use a household glass cleaner to clean the glass if you deem it necessary. You won’t need to clean any other part of briiv.

Q. How energy efficient is briiv?
A. briiv is low-powered via USB, using just 5V to operate. Over the course of a year, the estimated electricity spend is approximately £2/$3.

Q. What is your sustainability policy?
A. briiv uses as much recycled and sustainable material as is possible with the current scales of industry available to us. Over time, we hope to see more factories and suppliers using sustainable materials so that we can eventually get briiv to its 100% sustainable goal.

Q. How long do the filters last?
A. The filters are built to last up to twelve months, with the nano matrix component lasting up to three months. Don’t worry, each 1 year filter pack will have four nano matrix filters so you can swap them out after three months.

Q. What size room will briiv cover?
A. briiv will completely cleanse the air in a 6m x 6m room in one hour.

Q. What is your warranty policy like?
A. We offer a 2 year guarantee against defects and faults with briiv. We also offer a 30 day money back guarantee if you change your mind (minus shipping and handling), provided briiv is in the same condition as when it was taken out of the box and in its original packaging.

Q. Can I use briiv without WiFi?
A. Yes! briiv performs just the as well without a connection to WiFi or the app. briiv features touch buttons so you don’t have to have it connected to the internet in order for it to work.

Q. What are the exact details of the testing carried out on the filter?
A. So for the more intrepid, outlined below are the tests carried out:

briiv will improve the air quality in a 36m² (387ft²) living space in just one hour, with a delivery of 53 cubic feet per min of purified clean air.  

Continual flow tests have been carried out on briiv under normal and high load conditions, under EN 1822-4 conditions. 

Over all performance showed a 78% improvement in air quality in one pass, under low load and 80% under high load conditions.

Q. Do I have to pay import duty as an EU member.  
A. Any items imported to the EU from the UK (or vice versa) are subject to import duties and/or tax payments, which are due to the tax authorities from the country you are in. Unfortunately we can not change this.
