It can be safe, but it comes with significant risks. While genuine manufacturer (OEM) filters are guaranteed to fit your system and meet strict contaminant-reduction standards, off-brand or generic filters can vary wildly in quality.
Giardia cysts can infect humans and other animals. As in the case of Cryptosporidium, reverse osmosis or activated carbon block filters featuring at least 0.5 micron level filtration are recommended for their removal.
No, you cannot use just any water filter. Refrigerator water filters are not universal; you must use a filter designed specifically for your refrigerator's brand and exact model number. Using the wrong filter can cause poor water flow, leaks, or ineffective filtration.
Yes, specific water filters can remove Cryptosporidium. Because this parasite is typically between 4𝜇m and 6𝜇m in size, physical filtration is highly effective if the filter pore size is small enough.
To find the exact compatible water filter for your specific Frigidaire refrigerator, use the Frigidaire Filter Finder and enter the first 10 characters of your appliance's model number.
Frigidaire filters are NSF certified, the gold standard in water filtration. Compatible or look-alike filters aren't guaranteed to offer the same water quality. It's always important to use the same filter type that is currently in your refrigerator.
The team at Dave Smith Appliance Service put together a list of the most common issues we see.
Diarrhea, vomiting, stomach cramps, and weight loss are the most common symptoms. Dehydration is the main complication. People who have a healthy immune system usually recover without treatment. People with a weak immune system may get a more serious infection and need supportive medical care.
There is no single state with universally the "worst" tap water, as quality varies by utility. However, based on high contaminant counts, EPA violations, and population exposure, Texas and New Jersey consistently rank at the bottom.
There is no single "best" water filter brand because the ideal system depends on your home’s water quality, your budget, and whether you need an under-sink installation, a countertop unit, or a simple pitcher.
The best water filters for E. coli are those that use Ultraviolet (UV) light sterilization, submicron filtration (<0.45 microns), or Reverse Osmosis (RO) to eliminate bacteria. Top solutions include the Waterdrop G3P800 RO System (with UV, ~$849) and specialized high-flow UV purifiers for whole-house protection.
While the 6-month timeline is a standard recommendation by manufacturers, the exact answer depends on your usage and your home's water quality. For light usage with city water, you can often stretch it to 9–12 months, but going much longer risks contaminated water and appliance damage.
Yes, filtered fridge water often contains microplastics. Standard refrigerator water filters use activated carbon, which excels at removing chlorine, heavy metals, and odors, but they are not designed to capture microscopic plastic particles. Additionally, the internal plastic tubing of the dispenser can shed microplastics into the water.
Poop with Giardia is typically pale, light-colored, yellowish, or greenish. It is often described as greasy, fatty, or slimy (due to mucus) and has a very foul odor, often appearing as loose, watery, or, in dogs, "cow-patty-like" diarrhea. These stools may float or stick to the toilet bowl.

Reverse Osmosis (RO) systems and advanced multi-stage carbon/ion-exchange systems remove the most contaminants. RO technology forces water through a semi-permeable membrane to eliminate heavy metals, fluoride, and dissolved solids. For portable options, advanced pitchers using specialized filtration media achieve similar broad-spectrum results.
Boiling is the most effective way to kill waterborne parasites like Giardia and Cryptosporidium. Bring water to a rolling boil for at least 1 minute (or 3 minutes if you are above 6,500 feet).
New Jersey has the most highly contaminated drinking water system, with 556 systems. There are approximately 294,554 active lead pipes that need to be replaced. At least 379 water systems, serving more than 5 million residents, have detected elevated levels of TTHMs in their supply.
A Cryptosporidium (crypto) infection typically causes frequent, explosive, and profuse watery diarrhea. The stool often appears thin, clear, or frothy, and does not generally contain visible blood or mucus.
The single deadliest parasite to humans is Plasmodium falciparum. This microscopic, single-celled protozoan is the most lethal of the parasites that cause malaria. Transmitted to humans through the bite of infected Anopheles mosquitoes, it is responsible for the vast majority of the world's estimated 600,000 annual malaria deaths.
No, most people do not have gut parasites. While exact numbers vary globally, parasitic worms are relatively uncommon in industrialized nations like the U.S. due to modern plumbing, clean water, and sanitation. However, microscopic single-cell parasites do occur, and certain infections remain a significant global health issue.
The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.
Green = Run. The green run light indicates the compressor is running. If the indicator is dark it does not mean the unit is off. The compressor only runs when the compartment temperature is too high.
A continuous hum is usually a sign your fridge is safely keeping food cold. However, it shouldn't run endlessly. Modern, energy-efficient compressors are designed to run 80% to 90% of the time to maintain consistent temperatures, but if the motor never shuts off, you may have an underlying mechanical issue.
