Air Purifier for Bedroom Home Small Office – Fellowes Aeramax DX5 HEPA Filtration Captures 99.97% Smoke Odours Pollen Viruses - Quiet Operation (30db) CADR 139 m³/h - Relieves Asthma & Allergies

Have only been using the product for a few days, so it is difficult to judge but I will look at the filter soon.

As an allergic asthma and rhinitis sufferer since youth, by courtesy of the pesky housemite, I've lived more or less contentedly with prescription antihistamines, cortisone sprays and decongestants for decades. Somehow, the very existence of domestic air purifiers completely passed me by - no medical practitioner (out of about 5 in the past 30 years, including a consultant) has ever so much as mentioned air purification; one did suggest I should desist from housework and employ a cleaner; although he didn't offer one on prescription.Recently the medication began to lose its effectiveness, and increased dosages brought unacceptable daytime drowsiness; so I began research. Amazon rapidly popped up the dozens of air purifiers in the search context, and the process of kicking myself began. However, it soon struck me that every well-reviewed model has its one-star detractors, which doesn't help choice, especially with prices ranging from £50 to £900. My instinct was to buy the best, but that's a lot of money if they don't do it for you; so I chose to gamble £170 on this Fellowes, "just to see", and for no special reason, except that when I got to it, I was tired of looking. Interior design-wise it's a disaster - but it works. I started it up in my bedroom on arrival mid-afternoon, setting the fan on max until I retired, when I returned it to auto. That night, I had no nasal congestion without taking any medication - for the first time in as long as I can remember. Depressingly, it returned the following night - but it dawned on me that I had spent an hour or two before bed sitting in front of my desktop PC - which blows a steady stream of obviously dust-laden air into my face.In common with others, nights are worst, hence the bedroom siting. Lights and noise don't bother me, but to my ears, it's whisper quiet anyway on the lowest setting, which is where it spends most of its time, and on a breezy night, I wouldn't hear it. But if it finds pollution and ramps itself up to max, it could easily waken you. (I can understand others being bothered by noise, incidentally, but why lights ? If you shut your eyes to go to sleep, you can't see them...)Switched on for the first time, it defaulted to automatic, lowest output, showing the blue "Everything OK" light. This initially disappointed, as with another reviewer - until I realised that the lights only appear to indicate airborne chemical and odour pollution, not house dust. And it soon demonstrated its dust-control abilities. My ancient, uncleanable, central heating skirting radiators send out dust-laden hot air every year on startup, always producing the worst symptoms of the year; and when the central heating came on at 6am (well, it was summer, after all), it immediately wound up the fan motor to max, whilst the light stayed blue.The next night, it showed its other qualities; too many peas with dinner brought the inevitable nocturnal gaseous consequences; in seconds, the orange pollution warning lamp lit, and the fan moved to max. (If your partner is fond of peas, sprouts and spinach, this could be a worthwhile investment...) On the third night, I had to zap a mosquito with an aerosol spray, just a single brief shot, a good ten feet from the machine - and again within a second or two, it moved to max again, this time showing its red light. Makes you wonder about those fly-sprays... But last night it ramped itself up to Red-Light-Max for no reason I could detect, for about an hour. Still, better safe than sorry...I'm satisfied that both this method of mitigating housemite allergy, and this machine, are efficient and worthwhile - but only in parallel with other measures. Going into an air-purified bedroom will not instantly alleviate symptoms generated by exposure to a dust-laden atmosphere immediately beforehand elsewhere; the histamine-triggered inflammation and membrane permeability may persist well into the night even in clean air. I also doubt if it's much use purifying the air, and then, say, laying your head on an old, mite-infested pillow lacking an appropriate protective cover, or sleeping under an ancient duvet. And there's always the possibility that your rhinitis may have some other, perhaps additional, cause; I once asked an ENT consultant what could cause rhinitis, and he pointed to a list three pages long in a weighty medical tome.I've bought another smaller air purifier, the dinky Airvax, to sit by the PC, since I can't redirect the PC fan. This one is even quieter than the Fellowes, virtually silent, on the lowest setting, But it compares poorly in terms of specification, capacity and functionality, and is more or less the same price. Its saving graces are the supposed 3-year filter life, and miniscule energy consumption (it's 12V); and it appears to serve my specific purpose well. These two machines, in conjunction with other appropriate measures promise a worthwhile health improvement.

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.

ONLY HAD THIS FOR ONE DAY BUT UP TO NOW IT SEEMS TO BE WORKING GREAT, PITY THE MANUAL IS NOT MORE INFORMATIVE. MY LARGE FRONT ROOM IS VERY DUSTY ( HOPEFULLY NO LONGER ) BUT SINCE I HAVE HAD THIS ON FOR A FULL DAY, ON THE FIRST SETTING, AND LEFT ON AUTO, AND NO DUST ( AND MY GLASS TABLES ARE BLACK AND SHOW THE DUST IN ALL ITS GLORY ). AND YES YOU CAN TURN OFF THE IONISER BY HOLDING THE BUTTON FOR 3 SECONDS, I LEFT IT ON THO. NOW IT IS VERY VERY NOISY ON ANYTHING ABOVE THE FIRST SETTING, BUT ON THE FIRST SETTING IT,S NOT THAT BAD, BUT CAN STILL BE HEARD THO, WILL NOT NOTICE IT WHEN THE TV IS ON ( I HOPE ) I PUT THEM STICKY FELT FLOOR PROTECTORS ON MINE AND IT HAS HAD SOME EFFECT ON THE NOISE, SO ONLY FOUR STARS BECAUSE IT IS SO NOISY, AND ALSO FOR THE FACT THAT YOU HAVE TO REPLACE FILTERS ( CHARCOAL ONE EVERY THREE MONTHS, ON AMAZON FOR A PACK OF 4 = £27.99, THAT IS IF YOU USE IT ALL DAY ) AND HEPA ( £23.34 FOR ONE ON AMAZON ) EVERY YEAR, AND THEY ARE NOT CHEAP. I WILL UPDATE THIS IN A MONTH AFTER I HAVE USED IT MORE, BUT UP TO NOW I AM HAPPY WITH IT..OH AND WELL DONE AMAZON ORDERED AT ABOUT 5PM 16/03/2016, PAID FOR ONE DAY DELIVERY AND GOT IT 9AM 17/03/2016, SO AMAZING SERVICE..WELL HAD IT A MONTH NOW AND I HAVE TO ADMIT ITS NOT TOO BAD, DUST LEVELS HAVE REALLY DROPPED, BUT NOT GONE COMPLETELY ABOUT 97% ISH, SAYING THAT THO IT DOES WORK GOOD ENOUGH FOR ME. AND THE NOISE ON LEVEL 1, WELL THERE IS NONE ( NOW THAT IS HAS BEEN RUN IN ), BUT GO UP A LEVEL AND YOU KNOW ITS THERE, ALSO PICKS UP THE SLIGHTEST SMELL AND KICKS UP A NOTCH AND SEEMS TO STAY THERE A BIT TO LONG BUT I CAN LIVE WITH IT, SO WELL WORTH THE MONEY, I AM GETTING ANOTHER 1 FOR BEDROOM...WOULD I RECOMMEND? YES ITS A GOOD MACHINE FOR THE PRICE..
