Older and larger appliance had 3 different filters (which filers out particles depending on their size)Overall: I am very happy with this air purifier. I hope it gives me a long service life! I would highly recommend it!

I have been using Phillips air purifier series 800 AC08819/AC0820 for just over a week now and completely wowed by this product! I received in the box , purifier unit ,nanoprotect filter ,3 pin plug and manual it was super easy to install with quick set up, fool proof to be honest much to my delight! took less then 2 minutes to set up! just make sure to take the plastic off filter before powering on. Purifier has a clever sensor that picks up when the air quality is poor and automatically starts to clean , you don't have to do anything just leave on auto and let the purifier get to work. Love the one button touch for 3 different modes auto/turbo/sleep , I use auto most of the time but when I want the purifier to get to work quickly I switch to turbo, sleep mode is ...

I like the air quality light indicator circle around the button which has 4 different colours to indicate good/fair/poor/very poor to make you aware. Purifier works on many pollutants and fine particals and removes 99.5% as small as 0.003 microns! I like the fact there is a filter replacement alert light so you will know when to replace the filter without guessing. Maintenance of the purifier is easy to clean too ,wipe surface/air outlet cover daily or every other day with dry cloth , clean the air quality sensor with a dry cotton swab every two months , you can clean the surface of the filter around every 30 days with a soft wet cloth or with a vacuum cleaner but make sure it's not a high powered industrial vacuum as you could damage the filter. I just love this product and it has made a big difference to the air quality my family are breathing in which gives me reassurance! We are a family of four with two allergy sufferers in the household , this product as definitely made a difference to them , coughing/ sneezing /runny nose/itchy eyes is not happening as much as it was before using purifier. Purifier starts to automatically clean when it's picks up gases/odours and other pollutants such as pet dander /outdoor pollution /dust/pollen mould spores /virus/bacteria and much more .Nice points about the purifier it's easy to set up/use , it's compact but robust and not to heavy or big so you can easily move to other rooms in your home where you think the air quality is poor and needs cleaning. Will definitely purchasing a second phillips purifier and would highly recommend for asthmatics and allergy suffers .

Set it up and off it goes, Absolutely brilliant compared to the last unit I had. Small and compact, yet does the job brilliantly. The minute it detects anything that shouldn't be there, on it goes, and turbo goes on, I absolutely love it. I'm breathing easier, and the room smells good, The only complaint I have, is the noise levels, it is quite noisy on turbo especially. Other than that, highly recommended. Lost that 5th star, due to the noise of it and the expense of replacing filters. Phillips, can you try and get the cost of replacement filters down a bit please?

We live near not one, but two major roads as well as several mainline rail lines. In addition, the traffic on the local roads is bad, so there is always grit and other rubbish in the air.Since our purchase, we have noticed the air in our home being cleaner and somehow "softer".The Phillips Air purifier seems to be doing a good job and we are happy.It is very quiet and we leave on at night while sleep.We have noticed that when we cook (or doing other things in the house that may impact the air quality, the purifier detects this really quickly and immediately works at a higher rate to fix the air.Money well spent!!
I have bought three of these and have been pleased with their operation. The filter really shows how much dust there is in the air.Unfortunately, however, I have found it impossible to purchase replacement filters. I placed an order with Philips which they were unable to fill and they took weeks to process a refund. I have not yet been able to locate a reputable alternative seller. I'm very disappointed that I currently now have three useless appliances. I hope the supply issue is resolved soon otherwise I have really wasted my money.
The Philips AC0820 unit was really easy to unpack and set up, instructions were fairly simple to understand, and we were up and running within a few minutes. The packaging is minimal and came with a separate power supply and instructions. While the filter is preinstalled, it needs to be unpacked and the plastic packaging removed before use.The device is very easy to operate with only one control button for all settings and a power button to the rear. Just place it somewhere in a room, choose a mode, and let it do its job.The device felt solid, yet lightweight. A simple, yet premium looking product.When running using one of the modes (Turbo, Auto, Sleep), we really loved how fresh and clean the air felt during use, we swear that we slept better when it was on. ...

A simple, yet premium looking product.When running using one of the modes (Turbo, Auto, Sleep), we really loved how fresh and clean the air felt during use, we swear that we slept better when it was on. We continue to use it and are even tempted to get another unit for our living room.It was very insightful (and a little worrying) to know how bad our air quality can be in our house. Looking forward to trying it out in the summer to help with the pollen (this review was written in late autumn).The unit does a sleep mode, which is a nice touch! We've used this mode the most and have had it on most nights since setup without real issue.Size-wise it's not a giant unit but is a bit bulky if you wanted to place it on a side table, and we struggled to find a suitable place for it. If you don't have much space, you may want to look for a smaller model.Sleep mode is a really good addition to a unit such as this. However, while the fan noise is barely noticeable, it is still slightly audible for lighter sleepers. It didn't really worry my partner, but while nodding off I was aware of the background hum for a short while. We also felt that the sleep mode light could be much dimmer, as it's very noticeable in a completely dark room. Both are fairly small issues, but this information be of use to some.Overall, a great product with a couple of small niggles, but something we would recommend to those who have trouble with bad air quality. The jury is still out on how it deals with spring/summer pollen, but we have high hopes for this device.
This is really simple to set up straight out of the box, only took a couple of minutes.It’s intuitive and can tell if the air quality is bad, so it starts to do it’s job.There are 3 settings, I usually leave it on auto but as it’s in my bedroom I find the sleep option excellent for a quieter operation.The air quality indicator, this lets you know how bad the pollution is in your house, mine was poor but is good now, due to this device.I suffer from mild to moderate dust allergies but I’ve felt much better after running this for a couple of weeks.It’s such a compact design that you can put it virtually anywhere in the house, moving it from room to room, wherever you think it’s needed the most.The filter is replaceable but should last for about 3 years, ...

The filters are quite expensive, which is my only gripe with this product.Worth the money if you suffer from any allergies or just want a cleaner home environment.
We already own the larger Philips AC2889/10 model and purchased this smaller unit to the filter the air in another bedroom during allergy season. Compared to its larger brethren, this small unit is nice and compact and easy to use and more affordable. Unfortunately that is where the advantages end. The larger model has a truly silent mode which is ideal for night time while this model always emits a slightly annoying whirring sound even at low speeds. It also has limited speed options (only 3). Thus while we knew it was for smaller rooms, we were disappointed in the purchase. If you can afford it, buy the larger model, even for smaller rooms.
I received the Philips AC0820 Air Purifier to test & review under the Philips product tester scheme.On opening the box there’s a quick-start pictorial instructions in the lid flap that were very easy to follow. After removing the packaging from the nano-protect filter & re-installing in the bottom of the unit, I had the product up & running in less than 2 minutes. I then had a read through the written instructions and found them pretty similarly easy to follow.For first use I plugged in and turned on the purifier. It started up in auto-mode with the air quality sensor showing a purple-red colour and sounding like it was in top speed – about the sound level of an electric fan I’d guess. Within about 10 minutes the air quality display had changed to a blue-purple ...

It started up in auto-mode with the air quality sensor showing a purple-red colour and sounding like it was in top speed – about the sound level of an electric fan I’d guess. Within about 10 minutes the air quality display had changed to a blue-purple colour and then pretty quickly to just blue. The sound level/speed had also reduced quite a bit and it was then barely noticeable – about the sound level of the fan in your laptop.There’s also a turbo mode & a sleep mode (during which the lights dim down & the noise level is very quiet) though I’ve tended to just leave it in auto so far. It pretty much runs in the background 24/7 unless we move it to a different room of the house, but with doors open (we’re in a 3 bed bungalow) the light stays blue even when moving it from a couple of rooms away!I’ve been using the purifier for around 2 weeks now so it’s not needed a proper clean yet, however I’ve taken the filter out and given it a quick hoover & was amazed at the level of particles collected in such a short time.I can’t over enthuse about the difference this purifier has made around the house! My wife suffers from hay-fever and would often wake up with a runny nose & eyes even at this time of year & since we’ve started using the purifier she’s not had a single morning of symptoms. We got ourselves a new pet cat around 6 months ago & unfortunately my Mother had been unable to visit us due to her pretty bad allergies to both dust & pet dander. After using the purifier for 5 or 6 days we decided to try a visit & after a few hours she had no symptoms at all. She’s even now come for an overnight visit which would definitely not have been possible before (& slept with the purifier in her room overnight with no issues). Finally, we also have a small spare room that I’ve been using as a home office, but there’s been a bit of damp/mould in the corner this autumn. It definitely takes the worry of mould spores away when the air quality light turns to blue after around 10 minutes of the purifier running in the room & I can get on with my work without it playing on my mind.In short – easy to set up & use, runs in the background so you can pretty much forget it’s there, cheap to run & the results so far are beyond my expectations. Makes me wish I’d got one years ago!
I've been in the process of building an office while working in it simultaneously, but I found it uncomfortable to be in. This is because of the dust created by generally building work, so I bought this to trial it before moving it in the house. It works very well and it definitely clears the air and makes it more breathable. Because of the amount of dust on the floor, when I walk past it, it normally turns on a few seconds later. At maximum filtration it is noisy, perhaps 1/2 the noise that comes from a cheap summer time fan. I did place it in the bedroom on the night mode and although you could hear it, I don't feel it was loud enough to distract from sleep. The multiple modes are useful, though it's a shame it doesn't have a mode in between auto and sleep. I did ...

I've had it for around a month now and have no complaints other than the noise and I look forward to testing it in the summer as some household members have allergies and have difficulty sleeping.
