Rowenta Air Purifier Reviews: HEPA Filter and Formaldehyde-Free

Rowenta have been released for a number of years now and yet, some people are still complaining about coughing, sneezing, allergy and all sorts of illness related to unclean air inside your homes. So if you're still in doubt of getting yourselves these high quality and in-demand products, check our Rowenta air purifier reviews. This guide is based on the machine's air purifying performance, design and silent operation.

Most of air purifiers out there are only responsible of running basic air purifying tasks like filtering out dust, and human and pet hair. Users can just truly enjoy these tasks when set to lower speed settings because of their tendency to produce noise that can disrupt sleep. But if you want your family to breathe nothing but clean and fresh air even within your home, plus avoid cancer all at the same time, then Rowenta air purifiers is well worth considering.

Rowenta Intense Pure Air has discovered the formaldehyde-killing technology with its innovative patented NanoCaptur filter. Formaldehyde is a cancer-causing agent as identified by the World Health Organization. This is the most dangerous home pollutant that is found in pressed wood materials, perfumed candles, paints, cleaning products or still shampoo. Long term exposure to high concentrations of formaldehyde if not can lead to cancer, but can irritate the eyes, nose and throat and further increase the risk of getting allergies and asthma.
