Comparison of PUR Water Filters with Other Filtration Systems

Choose a water filter based on the impurities you want to remove. Choosing the right decision from so many possibilities might be intimidating. This article compares four Brita and PUR water filters’ abilities to remove pollutants.

Comparison Table of Brita vs PUR water filters

Containment Brita Standard Filter Brita Longlast Filter PUR Basic Filter
PUR Plus Lead Reduction Filter
Industrial Pollutants
Particulate Class I
Carbon Tetrachloride
Microbial Cysts
Chlorine – Taste and Odor
Nonyl Phenol
Bisphenol A (BPA)
Particulate Class VI


The Brita Longlast Filter and Brita Standard Filter eliminate chlorine, a major water pollutant that affects taste and odor. However, the Longlast filter can also minimize lead, a dangerous heavy metal that can harm humans. The Standard filter cannot remove or decrease lead. Both Brita filters reduce mercury, cadmium, and benzene.

PUR Lead Reduction and PUR Standard Filters eliminate chlorine and other pollutants. The lead Reduction filter removes lead, mercury, cadmium, asbestos, particulates, copper, zinc, and pesticides. The Standard filter removes several of these pollutants but not lead.

Brita and PUR filters remove pollutants differently. The Brita Longlast filter removes lead, but the PUR Lead Reduction filter removes copper and zinc. Carbon tetrachloride, tetrachloroethylene, Bisphenol A, and nonylphenol are also removed or reduced by the PUR Standard filter. It also reduces Atenolol, Carbamazepine, Estrone, and Cysts (Parasites).

Finally, evaluate which toxins you wish to remove while picking a water filter. The Brita Longlast and PUR Lead Reduction filters eliminate or reduce lead, a dangerous heavy metal that can harm humans. However, the Brita Standard and PUR Standard filters may remove or minimize many pollutants but not lead. To choose the best water filter for your household, evaluate your needs and tastes.

TDS Levels:

TDS levels are crucial when choosing a water filter. High TDS levels influence water taste and quality. This post will compare the TDS levels of water filtered by PUR, Aquacrest, and Brita filters.

Filter Type Unfiltered (ppm) 1st Pour (ppm) 2nd Pour (ppm) 3rd Pour (ppm)
PUR 543 530 556 512
Aquacrest 543 510 500 407
Brita 543 496 430 396


Unfiltered water had 543 parts per million TDS (ppm). After installing and running the filters, the initial pour of water had 530 ppm TDS for the PUR filter, 510 for the Aquacrest filter, and 496 for the Brita filter. After washing more water through the filters, the PUR manufacturer’s filter had 556 ppm TDS, the Aquacrest 500, and the Brita 430. PUR’s filter had 512 ppm TDS, Aquacrest’s 407, and Brita’s 396 in the third pour.

The Brita and Aquacrest filters had the greatest TDS improvement between the first and third pour tests. As more water passed through the PUR manufacturer’s filter, it did not improve.


Finally, while picking a water filter, evaluate your water’s TDS level and how much it improves. As the water was filtered through Aquacrest and Brita filters, TDS levels improved the most. Before picking a filter, check the TDS level of your water, as it can vary by region.

When selecting a water filter, TDS is only one aspect. Other considerations include the capacity to eliminate or minimize certain pollutants. Research and choose a water filter that suits your needs and preferences. Most water filters have a lifespan. Thus they must be replaced to continue lowering TDS and other impurities.
