Air Purifier For Bedroom Home Small Office – Fellowes AeRAMax Dx55 Hepa Filtration Captures 99.97% Smoke Odours Pollen Viruses - Quiet Operation (30Db) Cadr 240 M³/H - Relieves Asthma & Allergies

I have both the dx55 and dx95, I was so happy with these items orginally that I even convinced friends to buy them.This was 4 years ago.To date, both my DX55, DX95 and my friends 2 DX55 units have all broken down with exactly the same fault.They will all start up as they normally would whilst assessing air quality, but then after a couple of minutes they switch off and the lights on the front all begin to flash.The error makes no sense. There's apparently nothing wrong with the unit (I've taken both of mine apart and tested what I could). Yet, it doesn't matter what you do in terms of resets, they simply will not work.With most equipment, unplugging from power and then power cycling and leaving off for an hour or so is enough to discharge all capacitors and allow the unit to switch on with nothing stored.I left mine off for weeks and then tried them again only to find the same fault immediately.Oddly, after a few months I tried my dx95 again and it worked. So I tried the dx55 as well, it also worked!! For all of about 3 hours before the flashing lights started again.I've got a homedics tower air purifier in one of the bedrooms as well. I bought this before the fellowes. It's still running perfectly after all this time with no issues at all.I have of course changed the HEPA and carbon filters in the fellowes and reset the filter warnings.What really angers me is the money I've put into these things as well as the filters. Along with the fact that it's ultimately just a fan with a filter. So all it needs to do is switch the damn fan on and it'll work. Yet something on the board is deciding to stop this from happening.If this product just had a simple bypass to switch on the fan without the air monitoring mode it would still work fine.I know everything is working as when it's first powered up it all comes on and does it's job for the first couple of minutes.Given the fact this has happened to 2 of my own units and also to both of my friends units it demonstrates a 100% failure rate.So unless you want to have to spend hundreds more as soon as it's out of warranty I suggest you avoid all the fellowes models entirely and go with something else.When they are working (as they will for a couple of years), they do a great job. The living room one downstairs will pick up when I've sprayed on fragrance in the upstairs bedroom after about 10 minutes and ramp up to the third power level, rapidly cleaning the air and will settle down again as it senses it's clean. But working for a couple of years to then all fail is entirely unnaceptable.If there are any other owners that have had theirs for a few years running continuously (as they should be), it would be good to hear if they've had the same issues as myself and my friend.Overall, it works great but is guaranteed to breakdown.

A good air purifier which has now been working 24/7 for more than 2 years. Official replacement filter cartridges are expensive but this unit takes standard size 21 filters so you could use this https://www.amazon.co.uk/dp/B07Y7PRZVL/?coliid=IINAC4PN8MAK6&colid=JUNX4DLV31RY&psc=1&ref_=lv_ov_lig_dp_it.You get a HEPA filter plus 4 carbon filters for less than 12 quid. OK, you're going to have to wait for it to arrive from China but I think that is probably where the originals come from.

I've had both models DX55 (medium size rooms) and DX95 (large rooms).I found them not as good as the different makes on the market. Had used Bionaire and Puremate in the past and there were much more thorough in removing the particles from the air.I am personally displeased with the Auto mode and Aerasmart sensor which picks up greatly deodorants, hair sprays etc but does not detect pet fur in the air. I am owner of few chinchillas and their fur is very dense and yet the the reported that the air quality was "good", which was totally inaccurate. In order for this device to be effective the fan speed needs to be manually set to max which makes the machine very loud.Both air purifiers have now been returned and refund processed.

This is the second unit we bought. The first developed a sparking noise in the switch unit every time we turned it on. This was after 3 years of it being on every night in the bedroom. The unit cleans the air and we noticed it reduced stuffy noses and improved breathing due to reducing allergic triggers in the air.The unit has a very irritating feature - you cannot dim or switch off the blue light at night - so we made our own flip up cover. When left on a fixed low speed it does cycle between 2 slightly different speeds and hence the tone changes in sync with the speed change- but we got used to this . We bought a second unit due to the switch shorting issue described above and it also has the same slight pitch change on the fixed low speed but we already were accustomed to this and overall we like this air purifier.

Widely recommended at the time I first purchased this model in 2016. Replaced after two years and the only way we can live with the machine is to manually hold it down to the lowest setting, even if the red-light (HIGH POLLUTION SENSED) is indicating. Very poor if background noise is an issue for you - NOT suited for bedrooms for the noise reasons.Technically, it seems to do what is asked of it hence 2* but living with it is just too much. I shall be replacing this with another manufacturer
