they're silent because they're not effing WORKING
and currently, the number of working ones in our house is ZERO.
they both spazzed out. starting spitting and frying and then, dunzo.
these were the ones with the lifetime warranty. that cost a small fortune. that were going to purify my home.
and what's the deal with sharper image? they're rebranding?
that makes me ill.
anyone else care to vent? or explain? or offer alternative purification methods?
