Is this a genuine Dyson product?
It is sold as the Dyson Purifier Cool TP07, but under the PennWina brand name rather than by Dyson directly. Before buying, check who the seller is and what warranty comes with it, and weigh that against buying from Dyson or an authorized retailer, since after-sales support is where a reseller purchase can differ.
How does the automatic mode work?
Three sensors feed Dyson's algorithm, which diagnoses the air, shows what it finds on the LCD screen and in the MyDyson app, and adjusts the machine automatically. Leave it in auto and it steps up when pollution rises and settles down when the air is clean, so you don't have to keep changing speeds yourself.
Is it quiet enough for a bedroom?
Dyson gives it a Night Mode for lighter sleepers, which keeps monitoring and purifying on the quietest setting with the display dimmed. Dyson also says it is acoustically engineered to reduce turbulence and runs quieter than the previous model. As with any purifier, the higher speeds are for clearing the air quickly, not for sleeping next to.
What does the oscillation and airflow mode actually do?
It offers up to 350 degrees of oscillation to spread airflow across a room, and a Backward airflow mode that diverts the air out through the back of the machine, so it keeps purifying without producing a cooling breeze. That is useful if you want air cleaning without the fan effect, such as in cooler weather.
Does it really include 2 HEPA H13 filters?
Yes, the TP07 comes with two HEPA H13 filters. Dyson recommends replacing the HEPA+Carbon filter when the MyDyson app alerts you or every 12 months, whichever comes first, so the spare should see you through a second year.
Is it worth the money?
It is a premium purchase, and it earns its keep if you use both halves: a sealed H13 purifier with automatic sensing all year, and a strong oscillating fan in summer. If you only need a purifier, you are paying for a fan you won't use. Because it is sold under the PennWina name rather than by Dyson, compare the seller's warranty terms with buying direct before you decide.
