Water
Filters for Giardia
This is one of the newest technologies for dealing
with giardia. Water filters are popular and relatively
easy to use if they are working properly.
As waterborne pests go, giardia are easy to filter
out because the cysts are relatively large compared
to bacteria and viruses. Even water filters with large
pores will easily strain out giardia.
A few disadvantages of water filters include:
1. Expensive - Most run from $30 to more than $100,
and you have to buy new filters occasionally.
2. They clog up and become unusable. And sometimes
they are a pain to pump.
3. They require the most attention and care while
in use. If you start backwashing or dipping them in
the stream you're getting water from, you contaminate
the water filter system. That's something to remember
when you have a teenager filtering the water you'll
be using for your own personal use.
Easy
Pumping Giardia Water Filters
If
your only real concern is getting rid of giardia,
get one the less expensive water filters with large
pore sizes on the filter.
There are two advantages to this - they're cheaper
to buy, and they pump easier. The really small pored
filters that remove everything are harder to pump.
It takes more pressure to force the water through
the small pores on the filter.
Consider where you'll be using them. You aren't likely
going to get typhoid in North America. In India you
might, and will want a good filter for taking this
out, or else use iodine, chlorine dioxide or boiling.
