Dimplex DXAPV3N HEPA Air Purifier with Filter and Ioniser, White

This air purifier is absolutely brilliant, works really well and make the air clean and fresh, you can really notice the change when you walk into the room.However...The manufacturer no longer makes this product which means the filters are only sold via UK spares website, including delivery, you are looking at £30~ for a replacement filter.Keep that in mind if you go to buy one of these when they are super cheap.

Like others, the fan impeller came off within about a minute of turning this on. After some good discussion with Amazon, they agreed a partial refund, since a replacement isn't in stock. I then did the repair myself.Like another reviewer Leo said, get your mother on speed dial (unexpected AvE quote!) and only do this if your happy messing with mains voltage stuff.The motor is a 240V AC motor, rather than a DC computer fan, which is good. The ioniser has carbon fiber bristles, so efficient (thanks Big Clive!)It's far from silent but it's noise is not offensive. Full speed might be a bit loud for a bedroom, low speed is probably fine. everyone is different though.The filter fitment isn't great, it doesn't conform to the curve of the back plate, but it's probably good enough. Unfortunately this means the air coming out of the unit isn't fully filtered, some will have bypassed the filter.Exhaust is at the top on the front.The fix was easy. Four cross head screws and the whole device opens up and is simple inside. I added a bit of Loctite blue to the fan and pushed it back on the motor shaft.There is loads of unused space in this. More than enough to fit a SonoffBasic or similar to give you wi-fi control while hiding away all the mess, if you're into that sort of thing.

Nice looking nice size and quiet

Already had, so bought 2 more as it's very good for the price

Bought this to try and reduce the amount of pollen in the air and help reduce hay fever symptoms.Works fine - but as others have noticed, it sometimes makes a rather annoying 'clicking' sound.I took mine apart (see photos - don't try this at home, and if you do, make sure you un-plug the unit first, put on your safety squints, and have your mother on speed-dial) and it seems the electrodes for the ioniser module (the red and black wires that are dangling in the breeze) are prone to arcing over which causes an irritating crackling noise. I solved this by simply spreading the two wires slightly further apart.Not sure if this will reduce the effectiveness of the ioniser module, but I really just want this as a fan/filter.With that modification, the fan is not whisper-quiet, but certainly it's tolerable to have in the bedroom overnight.
