Last June, I emailed support@bolololife.com and asked them how to register the Baby Bottle Sterilizer because I couldn't find it on their website. The manual said that once registered, I would receive free HEPA filters. I included my order information from Amazon.

They responded "We have closed the registration entrance, if you want to get a free HEPA air filter , we can ship to you."

I replied to their email saying that would be great. I received a package of 4 filters within a week.
