Replace your Brita filter every two to six months, depending on how much water you use

The standard replacement schedule for a Brita pitcher or faucet filter is every two months if you fill the pitcher daily. If you use less water—say, a few glasses a day—your filter may last four to six months. Heavy users who refill multiple times daily should replace filters every month to six weeks.

Brita filters don't have an expiration date printed on them, but they do lose effectiveness over time as the activated carbon becomes saturated. Once saturated, the filter stops removing chlorine taste and odor as effectively, though water remains safe to drink. The two-month guideline assumes average household use of about 40 gallons per month.

Your water quality affects filter life too. If your tap water is heavily chlorinated or contains more sediment, the filter works harder and wears out faster. Softer water with less chlorine may let a filter last longer than two months.

Key Takeaways

  • Standard Brita pitcher filters last two months with daily use; faucet-mount filters last three months under the same conditions.
  • The filter's job is to reduce chlorine taste and odor, not to remove bacteria or viruses, so a saturated filter is less effective but not dangerous.
  • You can track replacement dates by writing the install date on the filter with a permanent marker when you first insert it.
  • Brita sells replacement filters in packs of two, four, or six, and they cost between $5 and $8 per filter depending on the pack size and where you buy them.

How to know when your filter needs replacing

The most reliable sign is taste and smell. If your water starts tasting more like tap water or the chlorine smell returns, the filter is saturated. This usually happens right around the two-month mark, but it can vary.

Some Brita pitchers have a small electronic indicator light on the lid that turns red or yellow when replacement is due. This light is based on the number of times you've opened the pitcher, not actual water quality, so it's a rough guide rather than a precise measurement. If your pitcher has this light, follow it as a reminder to check the water taste—don't replace the filter just because the light changed color if the water still tastes fine.

Write the installation date on the filter itself with a permanent marker. This is the easiest way to track when you installed it and know roughly when two months have passed. Most people forget the exact date otherwise.

Pitcher filters versus faucet-mount filters

Brita pitcher filters and faucet-mount filters have different replacement schedules because they handle different volumes of water. A pitcher filter typically lasts two months with normal use. A faucet-mount filter—the kind that screws onto your kitchen faucet—lasts about three months because you use it less frequently than you'd use a pitcher you keep in the refrigerator.

Faucet filters are also thicker and contain more activated carbon, so they can process more water before becoming saturated. However, if you run water through a faucet filter constantly—filling large pots or running the shower—it will wear out faster than three months.

Brita also makes bottle filters and dispensers with built-in filters. Bottle filters last about two months with daily use, similar to pitcher filters. Larger dispensers with spigots may last longer depending on capacity and how often you refill them.

What happens if you don't replace the filter on time

A saturated filter stops removing chlorine taste and odor, so your water will taste and smell more like untreated tap water. This is the main reason people replace filters—not because the water becomes unsafe, but because it becomes unpleasant to drink.

Brita filters are not designed to remove bacteria, viruses, or lead. They reduce chlorine and improve taste. If you're concerned about contaminants beyond chlorine, a Brita filter alone won't address that, whether it's new or old. A filter that's past its replacement date is straightforward less effective at what it was always designed to do: make chlorinated tap water taste better.

Leaving a saturated filter in place also puts extra strain on the pitcher or faucet mount if you continue to use it. The water flows more slowly through a clogged filter, and the seal can degrade faster if you're forcing water through a filter that's no longer working efficiently.

Storing and handling replacement filters

Brita filters come sealed in plastic packaging and should stay sealed until you're ready to use them. An unopened filter can be stored at room temperature for years without losing effectiveness. Once you open the packaging, install the filter within a few days—don't leave it sitting out.

Before inserting a new filter, rinse it under cold tap water for about 15 seconds. This removes loose activated carbon dust that can make your first few pitchers of water taste slightly off. Some people also soak the filter in cold water for 15 minutes before use, though Brita's instructions don't require this step.

If you buy filters in bulk, keep them in a cool, dry place—a kitchen cabinet or pantry works fine. Extreme heat or humidity can affect the packaging, but sealed filters are fairly durable. Most people buy a four-pack or six-pack to have replacements on hand so they're not caught without a filter when the old one wears out.

Cost and where to buy replacement filters

Brita replacement filters typically cost $5 to $8 per filter depending on the pack size. A two-pack usually costs around $12 to $14, a four-pack around $20 to $24, and a six-pack around $28 to $35. Buying in larger packs brings the per-filter cost down.

You can buy filters at most grocery stores, drugstores, and big-box retailers like Target and Walmart. They're also available online through Amazon, Brita's official website, and other retailers. Prices vary slightly by location and retailer, so it's worth checking a few places if you're buying a large pack.

Some people find filters cheaper at warehouse clubs like Costco if they have a membership. Costco sometimes carries Brita filters in bulk packs at lower per-unit prices than standard retail.

Frequently Asked Questions

Can I use a Brita filter longer than two months if the water still tastes fine?

Yes. If your water tastes and smells normal after two months, the filter is still working. Keep using it until the taste changes. However, most people find that two months is when the filter noticeably stops working, so replacing on schedule is usually the better choice to avoid that moment when you fill a pitcher and it tastes like tap water.

Do Brita filters remove fluoride?

No. Brita filters reduce chlorine, chlorine byproducts, and some other compounds, but they do not remove fluoride. If you want to remove fluoride from your drinking water, you need a different type of filter system, such as a reverse osmosis system or a specialized fluoride-removal filter.

What's the difference between a Brita Standard filter and a Brita Elite filter?

Brita Elite filters last longer—up to six months instead of two—and filter more water per cartridge. They cost more per filter but work out to a lower cost per month of use. Elite filters also reduce more contaminants, including lead and asbestos, whereas Standard filters focus mainly on chlorine taste and odor.

Can I wash and reuse a Brita filter?

No. Brita filters cannot be effectively cleaned and reused. Once the activated carbon is saturated, rinsing it doesn't restore its ability to remove chlorine. Attempting to reuse a filter wastes time and money compared to straightforward buying a replacement filter.

How do I know which Brita filter to buy as a replacement?

Check the model of your Brita pitcher or faucet mount—it's usually printed on the bottom or back. Then look for the matching filter type: Standard, Elite, Stream, or Longlast. Buying the wrong filter type won't fit your pitcher or faucet, so double-check the model number before ordering online.
