I've tried other brands of air purifier that didn't work well for me. One of my daughter has serious allergies and we try to keep the air flow around the house purified. The good thing about this product is that it is very easy to put together. Just open the cover and take out the plastic bag that is in between the air filter and purifier. Place the air filter and close the cover back. It looks very stylish, trendy and fits my home. I love the size and the fact that it doesn't make noise. The air doesn't go up like some other brands,its on the sides,which is so perfect for me. I noticed that my daughter's sneezing has been curtailed since we started using the 3-in 1 Hepa air purifier. The filter is very affordable and you can find the replacement around. I will recommend this product for household use just to take out particles ,dust and foul smell. Am buying another one for my loft. I love it.
