That means trichoderma spores, mould spores, yeast; this is why we use this level of kit in mycology. It’s not 100%, there’s still a (very improbable) chance of something going wrong, but 99.997% is a lot better than the 0% filtering ability of “not using a flow unit”.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThese are not particularly cheap (although they do last a long time), which is why you need to replace \u003c\/span\u003e\u003ca href=\"https:\/\/mycopunks.com\/products\/g1-pre-filter-for-flow-unit\"\u003e\u003cspan\u003eyour prefilter\u003c\/span\u003e\u003c\/a\u003e\u003cspan\u003e periodically - it’ll keep your running costs down. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eHow often should you replace the HEPA filter on your MycoPunks flow unit? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis is a bit of a “how long is a piece of string” question, but let’s try and work it out logically:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eIf you’re using a HEPA air purifier device at home, it’s recommended you’re changing them “at least once” every two years.

Rough way is to wait until things start getting contaminated on the regular and then realise why. Easy way is every six months or so, place an open agar plate in front of your flow unit when you’re working in front of it. Agar plate contaminates? Try another few in front of the unit on their own (you never know, it could be the 0.003% in action), and if they also go bad then it’s time to replace the filter.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAs a general rule, it’s good if you’re having a look at the filter every now and then to make sure it’s clean, you’re replacing your pre-filter when it’s dirty, and you’re not spraying any liquid at your filter (always spray your iso \u003c\/span\u003e\u003cspan\u003ebackwards\u003c\/span\u003e\u003cspan\u003e).
