I recently bought a Levoit 300 Series Air Purifier particularly for a family member who suffers from allergies (Paid Amazon affiliate link: https://amzn.to/3UOrw51 - Thank You if you decide to buy!). This is a best-selling air purifier on Amazon. So far at home I'm hearing a huge reduction in sneezing, so I really like this machine. OEM filters are not cheap though, and this video compares some after-market air filters with OEM filters from Levoit.
Let me know your thoughts and experiences about these filters and air purifiers below.
