Who runs this site

DownTo1 Purifiers (purifiers.downto1.com, part of DownTo1) is operated by Michał Zajączkowski, a sole operator based in Poland. Contact: info@downto1.com. This service is directed at users in India and China; it is not directed at the EU market.

What this site does not do

There are no accounts and no forms. Your answers and session live in your browser's local storage only and are never transmitted to us. 本站无账户、无表单；您的选择仅保存在您浏览器的本地存储中，不会传输给我们。

Visit statistics

• Umami, hosted on our own domain (stats.downto1.com) — cookieless, aggregate-only (pages viewed, referrer, country, browser type), no personal profiles.
• Google Analytics (gtag.js), which sets cookies (such as _ga) to distinguish returning visitors. The recipient is Google — see Google's privacy policy. Google's domains are blocked in mainland China, where this tool simply never loads; the site works exactly the same without it.

Outbound retailer links

Links to retailers may be affiliate links. Where they are, the click passes through an affiliate network's redirect before it reaches the retailer, and that network may set cookies on its own domains at that moment; we may earn a small commission at no extra cost to you, and this never affects the ranking. Nothing runs in your browser and nothing happens at all unless you click an outbound link. At the time of writing no affiliate network is switched on and every outbound link is the plain retailer URL; this section will name the network here as soon as one is.

Hosting

The site is delivered by a content delivery network, which briefly processes IP addresses in server logs for security and delivery.
