Actually, the filter will need replacing faster if more people are using it or depending on the usage rate by any one person. They have a finite lifetime. Pores get clogged, voids in the charcoal (carbon) get filled. At some point, the water no longer tastes as good because it's missing more and more of the untasty stuff as water flows through it and then it has to be replaced. The manufacturer should indicate a replacement schedule based on usage but also on time. Look for the difference between one person and two people using it equally if possible, that should tell you if your roommate's use of it will matter significantly. Possibly it won't matter because you would need to replace the filter sooner anyway for microbiological safety reasons than for plugging problems. It will depend on the system.

Also remember that for filters attached to the line, you do have to flush them with water before uses (if it has been idle any significant length of time) and you need to consider that water flow. Don't know the procedure for pitchers. Charcoal filters do need a good flush before the very first use regardless, to get rid of the "fines" (very small particles of carbon that will not be retained by the bulk filter and so will enter the water- not harmful, just startling if you don't expect to see little black particles in your glass!).

If you're getting an actual filter, not a water softener, then it doesn't matter if your roommate uses it. It's a mechanical device; it separates things rather than adding some outside substance that would cost money. Sharing won't change the cost in any significant way. If your relationship with the roommate is so hostile that you don't want her to get a few pennies' worth of benefit from something you bought, then a change in housing arrangements is probably in order.

some companies make a water filter in a to go container... save on plastic bottles.

I use the cleero filter that hooks on to the tap and fills up the pitcher..This is made by black and decker and gets better results than the brita.... I also bought it at Habitat for humanity.... new model in box $5, and 3 filters that last a long time $5. I filter everything.. even the water that I use to make sprouts...water for cooking vegetables, tea, coffee, etc...and if you don't want antibiotics in your water you should filter, not to mention flouride for some people and prozac.... for all that drop their med down the sink it is not purified out at the water filtration plant.

The original poster mentioned drugs and fluoride. So I was checking to see what the original poster was in need of; this will direct the type of filter that is needed.

Jennilyn- yes, of course most bottled water today starts out as tap water from the normal city line (already treated for microorganisms and toxins). That's a good thing, not a bad thing. But you are paying for the filtering system they use to remove mainly the treatment chemicals that give so much tap water a bad taste, quality control, hermetically sealed bottles (so they stay safe), bottling and transport. A good home filtering system also costs money (including replaceable filters and the cost of the water from the tap). You need to try to count up all the costs to decide if a home system will save you money and give you the results you want. you might need to at least attach an adapter to your faucet for some systems, but then you can disconnect after filling a tank in some models. I don't know recent ones, since my old discontinued Shaklee Bestwater System is still working. It has a hard plastic tank for almost 2 gallons of water that sets next to the sink, and hooks up to faucet. Be aware that there is always wasted water in such systems, so count that into your cost calculations. A pitcher system won't have any wasted water but the filtering is relatively limited (but that's all you may need).

By the way, since you're concerned about the plastic bottles: I'm very sensitive to stuff leaching out of food/beverage plastic (also to outgassing from other types). But I don't have problems with the plastic used for soda and Aquafina bottled water at least, although I use glass for storage of my own filtered water. Every plastic is different, some are less susceptible to leaching than others (or just have less to leach).

Dietitianbecky- you must be one of the lucky people who live in an area where the local treated water out of the tap actual tastes good enough to drink with wild abandon. I never have, except for a couple of years here before they "fixed" the sewers. Really, most places I've lived have terrible water. It may be reasonably microbiologically safe, but just doesn't taste good. Sometimes you can make it bearable by chilling and letting precipitates settle (we did that in one place when I was a kid, although it still wasn't very good), but I'm sure the poor taste of water in many areas is why people try so hard to drink it flavored (coffee, tea, soda, kool-aid, etc.). Bottled water in recent years has probably finally given people an idea of how good water can taste when the added stuff is filtered out (including the dozens of chemicals added to kill microorganisms and to remove harmful chemicals from the untreated water). Before bottled filtered water thankfully became fashionable, all we had was salty/acidic/carbonated "mineral water" in bottles. I even ordered delivery of a huge water cooler bottle of water for years in pursuit of plain, good tasting water. (It was good water, but since I didn't have a stand to fit it and am a wimp, it wasn't exactly easy to maneuver...) So count your blessings and yes, it's all about the taste for most people.

I haven't been able to stand our local tap water since they "upgraded" the sewer system a few decades ago... don't know the connection and would rather not. My experience has been that a filter system that combines a carbon filter and reverse osmosis along with normal particulate filtering makes our water taste great. The bottled Aquafina is about as good, and on the label they indicate carbon filtering and reverse osmosis as well (they start with municipal water in the locality of the bottling plant, I assume; you pay for filtering with such bottled water). When Aquafina is on a half price sale, it probably costs about as much as my home filtered water when all costs are considered.

But if you don't know what is needed in your locality (if you don't have neighbors with filters to taste test), you could start with a simple carbon filter and see if it works well enough. The water should taste good enough that you love to chug down a glass or two. If your water tastes much better if you let it sit loosely covered with a cloth out in the room for a day or so, that's a good clue that a carbon filter might help since it will trap volatiles that may be messing up the taste. A lot of disinfectants are added to tap water and some people like me can taste them.

I assume you live in a region that has water treatment. There is really no need to filter your tap water---unless it is for the purpose of flavor.

We used to have one of the Brita pitchers in the fridge, which was nice because it also kept the water cold. Maybe you could buy the pitcher and ask the roommate if she wants to share/pitch in for half the price of the filters (I always bought them in three-packs). Otherwise, standard rooommate agreement applies, and she keeps her hands off.

Ok so up to now I've been using plastic water bottles. The problem though is they're expensive, I'm worried about the safety of the plastic, and I read that 40% of bottled water is nothing more than tap water. I'm trying to be better to the environment too and I hate dragging all those bottles to be recycled every week. I'm just wondering if anyone could tell me of a good water filtering system. I live with a roommate so I don't think it would be useful to have something that attaches to the sink unless I can remove it in between uses. I'm not friends with my roommate and I can't afford to filter her water too. I'm hopefully looking for something that would remove as many impurities as possible (including drugs and fluoride). Thanks in advance for any help you can give. Oh yeah, it has to be BPA free too.
