TeraPur 600 Ersatzfilter 
(kompatibel mit AEROPRO100)

Dear Elizabeth,

Thank you for taking the time to write a detailed review of your experience purchasing your replacement filter from us here at Eoleaf! We are sorry to hear that our pricing has left you disappointed, but I wanted to take a moment to contact you directly about some of the points you raised.

First of all, we are thrilled that you were able to finally replace the filters in your AIRVIA device once they stopped trading. Many customers were left in the lurch when they closed shop, and we are pleased to be able to provide filters to the countless AIRVIA customers who were left with devices and no way to purchase new filters.

Regarding shipping cost, we certainly can understand your point of view. Unfortunately, filters are very voluminous. Although the Amazon era has given customers the impression that shipping doesn't cost anything, we charge you less than 50% of what shipping costs us.

Regarding pricing of the filters themselves, prices increased dramatically during and since the COVID-19 pandemic. Not only have prices increased for you, but they have for us, too. We have extremely slim margins on filters and, unfortunately, have little control over their pricing. We have made multiple efforts to keep prices as low as possible, even reducing our filter prices since last summer. We hope to do so again within the upcoming year to continue to make our filters more accessible to all of our customers. To provide some context, Eoleaf makes a razor-thing profit on filters (taking into consideration the price of the filters themselves, import costs, etc.). This is not a profitable item for us, and we are certainly not aiming to price gauge: this is just the price of a high-quality item. You will be hard-pressed to find a 5-pound filter (which is the weight of this filter) on the market, because most brands don't bother sizing it for it to be effective and last the whole year...

We are experts in the air purification field and can assure you that your money is going towards maintaining a device that offers some of the best air purification on the market. Our filters are expensive compared to some other products on the market, I cannot deny that, but they are big, heavy, long-lasting, and rely on 8 different technologies to bring you the best air filtration possible. We are proud of the products we have built and honestly believe we offer the best quality/price ratio. Air purifiers from the market's big players (Dyson, Philips, Levoit, and Blueair, to name a few) may be less expensive, but they are of lesser quality and require changing more often, contributing even further to your replacement filter budget.

I hope that this information provides some clarity regarding the situation on our end. We highly value transparency and running a business at a human scale, so it is important for us to clarify any misunderstandings directly. We hope that we will be able to continue to serve you for many more years to come.

Best regards,
The Eoleaf team.
