I have been using this vacuum cleaner since 2 years or so and I can say I'm glad I bought it at a very good price.
It is an affordable solution for cleaning small homes and apartments because it is lightweight, compact and small, so you can drag it easily around your home.
At the time I bought this vacuum cleaner I made a list of favorites among which there were a few models featuring water filtration.
I chose it because it comes from a trusted electronics brand and was specified that it doesn't spread dust in the air.
I wanted something that would allow me to clean my apartment without having to open the windows in the cold winter days.
Another good thing is that it uses two filter system: the popular Hepa and Cyclon. The Cyclon is the one placed on the tube near your hand. It collects all the big dirt elements, while the Hepa is inside the vacuum cleaner and is in charge with filtering the smallest dust particles. This one needs changing once a year.
In order to empty the Cyclon filter, which works like a traditional vacuum cleaning bag, you just have to drop the collected garbage into your trash can, unlike traditional dust bags that you have to shake in the air and inhale all the dust.
The smallest dust particles will be in the Hepa filter, hidden inside the vacuum cleaner, and you'll need to wash it with water once in 6 months.
The guys from the store I bought the vacuum cleaner from told me that the Hepa filter needs to be changed once in 2 years and I just changed mine with the second Hepa filter included in the box.
There's also a paper bag included, but I am not interested in using it. I guess it is intended for those who want to clean and drop the contents and the bag.
About the price for the Hepa filter - I don't know how much it is, but let me assume you could get one for about £25.
The Hepa filters are called anti-allergenic filters.
And regarding the noise - it is at the same level as of most of the vacuum cleaners.
