Bosch Dry 4000, Dehumidifier, For Rooms up to 33 m²

Works amazingly well, I couldn’t believe the water it removed from the house (a full tank almost daily). It’s not very loud, but can hear it. Simple to use and understand. We have a three story 1930’s semi and suffered quite a bit of condensation (despite new windows) and mould in poorly ventilated spaces (in cupboards, behind furniture, etc). Been using it for about a month or so (Jan/Feb) and have it set up in the centre of the house, really pleased with it. One thing, suspect the same with all dehumidifiers, we find we get itchy eyes when it is on its maximum dehumidifying setting (40%) and left on overnight. Have now adjusted it to about 60% and eye much better.

Great little dehumidifier, tucks away quite nicely and is not too loud. Turns on every 10mins or so to check humidity on automatic and turns off if not needed. Relatively light so can move to other rooms if needed. Seems to deal with my 3 bed house fine on its own. Easy to setup, not really much to it other than attaching the tank. Only gripes are if you live in a humid home, the tank is not that big so you may have to empty it every day or two. The tank also is not fully sealed so leaks slightly when emptying but it's not really an issue, especially if you use the hose.

I’ve gone through three pro breeze dehumidifiers over the past 3-years and decided to try this Bosch. First off, it’s a lovely looking bit of kit. White body and black top with classy white LED display. On start up, it’s quiet, very quiet and has all the usual options of setting humidity, laundry mode and child lock. I just set it at 45% and leave well alone. The machine will hit the humidity level then sleep, with the LED pulsating. The water container is sealed, bar a pouring spout which allows you to decant your water into the sink or toilet cistern. It’s been on for two weeks solidly doing its thing and it’s been a joy to own and to look at. It just feels and looks like quality. I tried to register with Bosch but the product label was missing something, but Bosch said they’d honour a 2-year warranty despite the registration failure. It’s a little more expensive, but you get what you pay for. Can’t fault it so far.

I was really impressed with this product. I have been researching and came across an article that said you could potentially save on heating by using a dehumidifier. Ever the sceptic, I thought I would give it a try. I set it up on the landing, between 2 bedrooms. After I had used it for about 12 hours, the landing window did not have any condensation on and the air really did feel warmer. The water bottle on the unit was around 3/4 full but it is very easy to empty. I purchased the additional filters so it should further improve the air quality in our upstairs rooms. You can use the settings for the unit to run automatically and reach your desired settings. The unit also has an alarm when the water bottle needs emptying. I am really impressed

I chose this over the other offerings due to its lower wattage and running costs compared to other popular machines. I'm also a fan of Bosch being the user of many of their power tools. Wifey is surprised by the amount of moisture this collects, the stuffy damp smell is gone from the north facing spare room. It's now being utilised in the main bathroom due to the existence of mold on the ceiling and walls, early days but I'm supremely confident this machine will alleviate the unsightly issue.

The machine is excellent in performance and quiet too. The only downside is that ( as previous reviewer) mentioned there is absolutely no where to register on the Bosch website. You have to email Bosch to get them to tell you have a guarantee

I have had the 16L version for a couple of weeks and am very pleased with it. It’s compact but powerful enough to keep my open plan lounge and kitchen (and probably a lot more) at 50% humidity with ease. Don’t be worried about the 2.5l water container as the quoted 16l per day is a maximum (presumably in very humid conditions),In my house I’m emptying it about every 12 hours. It’s pretty quiet, so much that you don’t really notice it when it’s on. I am just running it through the day but it’s doing exactly what I wanted it to.

The 4000 is a great machine. Bought this to put upstairs in our upstairs spare room in 2 bed semi where we hang clothes to dry and bathroom is upstairs too. It collects so much water and helps to dry the washing super fast. Very happy with it and amazed to see how much water it collects - I empty it every 48 hours if clothes have been hung up in that time.
