I would like to perform a test to see if my Brita Filter cartridge is still effective. What would be your suggestion in designing an experiment to test the water filtered by these cartridge?

I have access to use microscope, petri dishes, incubator, x-ray diffraction machine, gas chromatography, pH meter, and regular chemical experiment equipments.

thanks in advance

You need to test the water before and after filtration. This will let you determine what, if anything, the filter removed (or added) to (from) the water.

The microscope can be used to detect particulates. The petri dishes, and incubator can be used for microbial (bacteria and fungi) growth, but the shouldn't be any microbes in your drinking water before you filter it. The govenment has a TMDL of 0 for all microbes.

I'm not sure how X-ray difraction works and I believe gas chromatography take a small amount of a solid material and vaporizes it, so I don't think it would work.

You can test pH before and after, but that won't give you very much information.

You may be helping a lot of people to save money and keep healthy by answering and share your experience using Brita filters.

I found that Brita Filter replacement cartridges and similar products are extremely expensive. Not mention if you have to pay for the water+sewage as well in your monthly utility bill.

1. Is it good for pregnant woman to drink water filtered by brita instead of buying bottled/distilled water?
2. Is brita filter cartridge contains only activated carbon, what are the white/cream particles inside?
3. Is it easy to regenerate just by boiling it, or you have to reactivate the carbon by baking or burning it?
4. Can you replace the carbon with regular activated carbon (with the same particle size)?

It depends on what you are wanting to filter out of the tap water. Do you know if your tap water contains an elevated level of lead or other heavy metal or chemicals other than the chlorine added in water treatment? If not, I suspect that most filters are very effective far beyond their recommended capacity, since that is based on the worst possible level of contamination in any water system. If you want to test this, use the filter for a while beyond the recommended replacement date, and test the water for chlorine with a swimming pool test kit. If you don't have a pool or know someone with one, call local pool maintenance companies & see what they would charge to test it for you. I am quite certain that there is no way to regenerate activated charcoal/carbon.

The truth is that TAP WATER is just fine in most communities. State laws regulate frequent samplings, inspections and reports on the content of our drinking water.

Lugging in jugs of bottled water to drink in your house is simply not necessary.

I can get a gallon of spring water from the supermarket for 90pence. Is it worth getting a water filter?

I used my filter for about two months before replacing it. It really depends on the amount of calcification in your water. If the magnesium is very visible on the surface of hot tea, you'll be using it about a month.
The other thing is the reduction of plastic waste from bottles.
In Northern England the water is very low in calcified deposits, so the water doesn't really need filtering, just allow the light chlorine aroma to disappear. In the places like the South East, the water is horribly calcified.

I just change my filter cartridges and now sure what to do with the old one. Should i put it in a trash can or in recycle bin ?

Get a small padded envelope

Address it to Brita Customer Service, use the address listed on their site for problems

Write a hand written but readable letter saying you tried using the filter but were not satisified with it. They might send you a free one.

Otherwise, I would just trash it
