How Does Giardia Get into the Water?

As you all know, Giardia is tiny parasites that can enter anywhere they want, and we can not remove them by hand.

Therefore, you should know how to do these tiny particles and what conditions will be more opportunities to enter. For example, it can get into the water through contaminated food through person-to-person contact when they spit into the water and do not clean the surface properly.

These parasites are generally found in lakes, ponds, wells, and swimming pools. When people throw diapers into the water, people may sometimes discharge their diarrhea into the pools and spas.

Many people do sex in many different ways. For example, through anal sex, Giardia may spread into the water when they wash their body parts in the water. This water may leak into the river, ponds, or lakes. 

You should never eat uncooked foods that are usually contaminated with different parasites. In this way, these tiny parasites can get mixed into the water. And many people do not use water filters, and all kinds of filters may not remove Giardia from the water. That’s why people should reduce the spreading of waterborne parasites.

How to Buy the Best Water Filter for Giardia & Cryptosporidium?

There are many different types of water filters in the market. So you might get confused about which one to buy. You need to check the filters internally and externally.

Otherwise, Giardia and Cryptosporidium may not be removed from the water that makes you sick instantly.

Therefore, before you buy water filters for eliminating microscopic parasites, you should know what the features you need to use in the water filters are.

  • Types of filters
  • Accredited certification
  • Price

Types of Filters:

When you go to market or search online, you will see various water filters. For this reason, you might be confused, and it is obvious! As the days pass, the manufacturers are trying to improve the model of the water filters.

But do you know all types of filters do not work for removing all kinds of harmful chemicals? Therefore, you need to know about the suitable water filters that can help you say Goodbye to microscopic fragments like Cryptosporidium and Giardia. 

The most demandable filter for eliminating or reducing these types of parasites is only the Reverse Osmosis Filtration System. 

And the filters that are capable of operating by micro-straining can also help you remove or reduce the number of these kinds of parasites from the water filters. 

The Microstraining filters are generally of two types: absolute 1-micron filters and nominal 1-micron filters. All 1-micron filters work efficiently to eliminate Giardia and Cryptosporidium from these two filters.

Accredited Certification:

When we check for something significant, we generally want to see some paper for the formalities or evidence for getting a university chance is also the same case for the water filters.

As the water filter is one of the essential parts and parcel of our life, we must check the certificate before you purchase the water filters.

If you are looking for an effective water filter that can eliminate the numbers of Giardia and Cryptosporidium, the credentials of the water filters should be labeled to NSF/ANSI standards 53 and 58.

These different numbers are evidence and ensure the removal of these harmful microscopic parasites. And you should check whether the filters have an absolute 1 micron or not. 


Price is one of the essential things to understand. People may think expensive water filters can work effectively.

Buying the expensive water filter is okay, but do you know if you do not buy an appropriate water filter for proper functioning, no matter what, Giardia and Cryptosporidium will stay in the water!

As I have said, Reverse Osmosis and Micro-straining filters are the filters that can work effectively; if you buy different filters like carbon block filters, Ultraviolet filters, EPA approved filters, it won’t work for removing Cryptosporidium and Giardia.

And the filters that can remove these types of parasites are very expressive. So before you buy, think wisely. To the best of my knowledge, no filter can buy 100% parasites.

So if you are thinking of spending money to buy a water filter, it would be a great idea to purchase a water filter that can eliminate 99% of microscopic fragments.
