Several different water filter kits are available depending on your wants & needs. All of our kits are DIY, configurable, and feature simple, non-electrical operation. We have 2 types of ceramic filter cartridges, a ready to use portable roll bag that can supply extra water for cooking and washing as well as drinking, a stainless steel model for permanent kitchen use, and our new versatile "all in one" Homespun water filter kit that can be used as a straw, with a drinking bottle, in line with a hydration pack, or in a bucket system.

If you wish you can buy the buckets pre-drilled from us but it is highly recommended that you procure your buckets locally and DIY. It will save quite a bit as the bucket systems do not qualify for free shipping due to their bulk.
NOTICE: Due to legal ambiguity in certain statutes in Iowa we are suspending shipments there pending further notice. We regret the inconvenience this may cause.

Replacement filter part number: BC-0103
Gravity Fed Water Filtration System (SK-1001)
Our Price: $41.75

All the needed materials to construct a basic gravity fed drip system: 2 pre-drilled, food grade buckets with lids, ceramic filter (either regular or viral reduction), spigot, siphon, and sock. (Filter mounting is offset to allow for the addition of one or two more filters if desired.)

Use to make potable water 'off the grid' or to have as an emergency water kit 'just in case'. (30,000 of these systems were shipped into Haiti after the earthquake there, and 10,000 were shipped to Japan after the tsunami. In both instances bottled water was hard to find and expensive.)

The buckets are bulky and expensive to ship hence this product does not qualify for free shipping (shipping charge is calculated separately on the checkout page). If you can drill a few holes in plastic you can lower your costs significantly buying just our 'emergency kits' (BC-0102 or BC-0502) and sourcing buckets locally.

NOTE: The buckets are pre-drilled but the kit requires some assembly by the end user. (Assembly instructions are provided)

This hanging water bag contains two ceramic filter cartridges and pre-filter socks in the bottom of a 3 gallon bag. Ceramic pores strain out bacteria, activated charcoal treats for a broad spectrum of chemical pollutants (agricultural run-off, boating oils, etc). A flexible tube from the bottom of the bag is used to speed flow rates and direct the filtered water to your containers.

The unit can work on any fresh water source and requires no assembly. Flow rates of over 5 gallons/hour once the filters are saturated. Bags come in Camo (shown), Black, and Dark Blue. The entire kit rolls up into a compact package less than a foot long and 6 inches in diameter.
