We installed 16oo sf bella wood floor in my house in 2009. Right after the installation, all of my family members started to have allergic reactions, headache, dry eyes, burning throat, skin rash, etc. We did indoor air pollution analysis, and found a high concentration of formaldehyde (25 times higher than it should be) in my house. Wood floor material analysis found it contains a large amount of formaldehyde in the top finish of the bellawood floor. Please contact me if you have the same experience. 713-829-2172.
