QT3 portable air purifier – FAQs

Why is there a gap between the filter and the vent?

The QT3 is designed as a global product and works as a cooling fan and an air purifier. Our tests and data actually show that keeping a small space between the filter and the side wall actually increased clean air and CADR and encourages air mixing making it ideal for reducing particulates in a room or confined space like a car.

However in the UK, we have little use for a cooling fan and high cases of COVID so the space can appear unnerving, especially if you’re concerned about sitting downstream from a COVID carrier. To address this issue, we will be sending out all new QT3 orders with side strips, so you can choose if you want to use it. There is no change to the QT3 unit or the filter, the side strip just closes the gap and produces a stream of clean, filtered air. Below is a video highlighting how to insert the strip.

Please note that when inserting the filter, the filter have the arrow on the top, ie no padding. If you put only non-padded side of the filter at the bottom, you will have a small gap at the top corners.

If you have previously purchased a QT3 from Smart Air UK, please email [email protected] providing your order number. Alternatively, you can tape the filter to the front part of the QT3 using ordinary wide tape, this can stay in place until it is time to change the filter.

It’s important to know that for COVID protection, the QT3 should be considered one tool in your arsenal for self-protection, much like hand washing or wearing a mask is just one part of the puzzle. If you are concerned that there may be COVID carriers nearby, then we recommend you wear a mask, as they provide the highest level of filtration (although again, they still don’t offer 100% protection).

Can the QT3 be plugged in 24/7?

There are 2 version of the QT3, the home and the travel. Only the travel version is available in the UK and we don’t recommend to leave it permanently plugged in. As with all rechargeable battery electronics, if you leave it permanently plugged in, it will eventually impact the charge time

Can the QT3 travel be used even after the battery is depleted and will no longer charge?

The QT3 comes with a lithium battery which is rated to last at least 300 full cycles of charging and discharging. Similar to most smart phones, we expect the battery to last 2-3 years under normal usage conditions.

After this point, the battery may not be able to hold as much charge as when it was new. However your QT3 will still be useable when permanently plugged in.

Can the QT3 Travel version be used still if we remove the batteries? (to preserve battery life)

It is not recommended to remove the battery from the QT3 Travel. Without the battery installed in the Travel version, you may see unexpected results such as lower airflow or higher current or power usage.

Is the battery on QT3 Travel version replaceable?

Replacing the battery in a QT3 is not possible because of the way it was built in.

Can the QT3 Travel version be brought to the airport?

The travel version has a Latium battery so it can only go into carry-on luggage, but please make sure to check the chosen airline’s baggage policy before the flight.

Why isn’t the CADR shown for medium and low setting?

The reason why CADR for the QT3 isn’t shown on the other settings is that standard (GB-18801) specifies a minimum testable CADR value of 30 m3/h. It’s expected that the QT3 on low and medium would be below this level.

Can the QT3 Travel HEPA purifier be used to clean the air in a bedroom?

The QT3 is a portable air purifier for travel but we ran the test in our offices and it can clean the air in rooms up to 15m2, just slowly – Can the QT3 Air Purifier Clean a Whole Room? Real World Test

    This is such a great little device. We’ve used it when out and about in cafes and meetings. Love it!

    I love the QT3. I had attended a workshop with SmartAir in Beijing years ago and found their DIY air filter invaluable. The QT3 arrived very fast and when I opened it I was pleased to find it was absolutely adorable. I was concerned it would be too big but although it is bigger than some other “personal” filters, I do feel it is perfectly formed. I have taken it on a day trip with me and it wasn’t too obvious or too loud on the train table. It is nice and light too, so easy to cary in a big handbag. I feel so much better to have this air filter in my life. I just wish more people knew about these!

    Excellent service and super fast delivery. I really like the shape and the retro feel of the QT3, it is very light and easy to carry too. It comes with clear instructions and is not complicated to set up, at all. I love the fact that is very quiet, as I bought it for my child to take to school. The battery life is really good, and I think it is a great idea that there is a small compartment to store the USB cable in. Powerful yet quiet, portable and simple to operate, safe and effective, it does exactly what it promises. My only suggestion would be, provided it is safe and will not compromise the efficiency of the system, to reduce its width as I think it is a tad bulky. Nevertheless, I feel reassured in my purchase, I am very happy with the product and I will be using Smart Air for all future purchases.

    This smart looking, light, and easy-to-carry air purifier arrived quickly and in sensible packaging. Love the retro styling! I plan to use it in the car when sharing journeys with family members who necessarily have more exposure to covid than I do…a very welcome layer of protection and peace of mind. I will only ever buy from Smart Air because I trust them to sell the best, independently tested purifiers at reasonable prices. Grateful to have this little purifier at the ready!

    Easy to set up and performed quietly in the office, even on the highest setting. Initially ran on a fully charged battery for several hours before needing to plug in. Light and portable. Gave me some extra assurance re: COVID. A colleague said the design reminded her of a vintage handbag! Perhaps Smart Air could look to make the buttons more user friendly for visually impaired people and label the filter replacement light and button so they are more intuitive. Overall a great little product and will hopefully prompt some more awareness of the air cleaning solutions!

    Very easy to use, not noisy. Small and light enough to be held on a lap facing you during medical appointments. Using it in a hospital waiting area gave me the confidence to be there. Good battery life but get a powerbank for longer than 2hrs use.

    Perfect size, smart looking and light. Good battery life. Can also run using USB C cable. Quiet too. Very quick delivery.

    We received our QT3 today, much quicker than expected! Very lightweight, and surprisingly powerful for it’s size, perfect for taxi rides, hospital appointments, even just as a cooling fan when the weather calls for it! Comes with USB C cable and can be run from internal battery or a usb power bank. You can’t put a cost on peace of mind. Thanks!!
