Pure Enrichment PureZone Mini Portable Air Purifier - Cordless True HEPA Filter Cleans Air & Eliminates 99.97% of Dust, Odors, & Allergens Close to You - Cars, School, & Office (White)

I like this HEPA. It's better than the Munchkin, more forceful. However, the filters are generally unavailable in the UK. The company is based in the US and all I've managed to get from them is that the filters are available on Amazon (they're generally not) and via a wholesale distributor called IOCA, who they recommend I contact to ask where the filters are here. Unsurprisingly, a multinational wholesaler has ignored me. So unless you can see actual Pure Enrichment brand filters anywhere, I wouldn't recommend purchasing this as a long-term investment. Maybe you could check the EU, if you know anyone on the continent. The HEPA is, however, smaller and more powerful than the Munchkin, and works well on flights and at the dentist. So if you're clinically vulnerable, it may help to save your life, since apparently we can't get that as a basic tenet of British medicine anymore. Live long & prosper.
