Eco Four TwentySet of 2 Replacement Filters Personal Air Filter

Edit: leaving my original review at the end of this, but I HAVE to update this.I heard from the owner of this company almost within the day after posting this review. Without going into detail, suffice it to say this was more than made right. The owner delivered honestly some of the best customer service I've ever heard of.And, bonus: we discovered that the only reason the filters were clogging so fast was due to condensation. Swap them out and let the filter media dry completely on the inside? And they are better than new! We've been rotating the same 4 filter cartridges for about 2 years now, and they still work just as well as they did on day one. Not a single whiff of any smoke will you find in my house! LOVE this product.Original review:We originally loved the Eco 420 filter. The one that came IN the unit worked great and lasted a fair amount of time. However, the refills were a huge disappointment. They lasted only a few days at most; one of them lasted not even 2 full days. There was no fluctuation of use on this end; we expected each filter to last the same 3 to 4 weeks as the original. We were sorely disappointed... not only with the filter performance, but also with the lack of response when I inquired about warranty replacements on their website. I received no response whatsoever.So much for standing behind their product.

Work great!Delivered faster then i though good job!

Where do I even start? Superb product for all your filtering needs. As someone who needs to be discrete at home, this filter allows me to enjoy myself without worrying about any residual odour or smoke. While at the same time, I can but refillable filters so I do not need to discard my plastic smoke b… other type of filter after use which makes me better about my choice. And now they have plant- based plastic which is even more eco friendly?And to top it all off- getting a handwritten note informing me of this change is the mic drop of all mic drops. Wishing your team all the best and will continue to be an avid supporter of your brand. 🤘🏼

I've been using these filters for awhile now and I have to say I favor Eco Four-twenty over other brands.First off stylish look and easy to use. Comfortable silicone mouth piece with an over the lips tube rather than a lips on. Replacement filter are easy to change out and sell in two packs, always have a spare on hand. Cost of two filters is cheaper than the cost of a single filter with others.Filters, while a lot of people will disagree about how long these filters will last. And while I have not sat and placed a count on exhales I will say that there are "a lot" of factors which play into the length of time a filter will last ie…. What your pushing through the tube first of all, cigarette smoke, cannabis smoke (this includes strain types), the way you're smoking (rolled, pipe, water pipe) etc. some push more moisture than others. Are you have group sessions, the more smoke being pushed through the tube creates more moisture in the tube for a longer period of time. These are all factors that play into the life of one of these filters.I use these filters everyday! And with the above factors in play i.ve had a filter clog in as little as a week but most last 3- 4 weeks. Yes each. Again what you're expressing through these filters plays a big role. Would I recommend the Eco Four Twenty Filter to others, Yes its a solid product. Customer service is awesome and Michael the owner reaches out to customers, always a plus.

These are so small they slip into a pocket, I've mastered Vaping in public toilets even in hospitals and planes both with smoke detectors and never even once have been given a "look"Pro tip: buy a few of these filters, 4 or more, number them and cycle them around letting them fully dry out inbetween uses, if you do this properly they'll last you a year easily ;) better yet do what I've done, buy 3 sets of 4 and never buy another one
