^ Winix NK105 replacement filters estimated cost
Winix NK105 is of course more pricey than Winix NK100 due to the added WiFi-enabled features. Is it worth the extra bucks? Personally we would go for it simply for the comprehensive scheduling feature but to most people we would assume Winix NK100 would do just fine. On filter side, the same complaint we have with Winix NK105 is the expensive all-in-one cartridge filter that that requires complete replacement if either one of the filter is exhausted. Nonetheless, there are plenty of discounted deals online for Winix NK105 and we recommend searching it via Amazon website.
