【Disaster Prevention】Is your drinking water supply sufficient? 4 types of portable water purifiers that can be used multiple times and remove contaminants with high precision

Securing drinking water is crucial during disasters and outdoor activities. With Greeshow's portable water purifier, one filter can purify up to 30,000 liters. Personally, I'm interested in the convenient electric type!

The recommended amount of drinking water is 1L per person per day

According to the guidelines from the Ministry of Agriculture, Forestry and Fisheries and the Tokyo Fire Department, the standard for drinking water is 1L per person per day, and when including cooking water, it is set at 3L. During emergencies, it is recommended to stock at least 3 days' worth of water, and ideally 1 week's worth, but keeping that many plastic bottles at home can be quite challenging. Particularly if you also need to secure emergency food supplies.

In this regard, portable water purifiers are compact, saving space, and are highly portable. They can filter water that is unsuitable for drinking using special filters, allowing you to secure only the necessary amount of water when needed, which can be considered ideal.

Greeshow offers four types of portable water purifiers. They include the world's first (according to the manufacturer) electric type, and a foldable version that is easy to use even in climbing, each with its own unique features. Let's take a look at their characteristics.

Additionally, it features an LED light function that can be useful during power outages.
