What the CPSC Data Shows
Filters (CPSC product code 4005, in the Floors, Walls & Ceilings category) generate an estimated 563 emergency-room visits every year in the United States, adding up to roughly 11,255 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 34/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 17% over the last five years, with the busiest year on record being 2024 (1,145 estimated ER visits) and the quietest 2011 (180 estimated visits).
The single most common ER diagnosis for filters is laceration to the finger, accounting for approximately 2,417 visits across the 20-year NEISS window, followed by contusions, abr. to the eyeball (642 cases). The 55-64 age group absorbs the largest share of injuries, about 2,056 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 6.8% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 30 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how filters fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Regarding the 'express water' reverse osmosis system which contains a UV lamp. Based in CA and currently available on [REDACTED]. The UV lamp O-ring is not lubricated and is the wrong size. The o-ring can easily cause a leak into the high voltage lamp which is connected directly to the power supply. I contacted the company and was met with a PR-wall. They know this is a problem and they are playing the plausible deniability game.
I purchased a new HEPA filter insert ([REDACTED]) and charcoal pre-filter (HON38002) for my old [REDACTED] air purifier. The products came from AllergyBeGone (866-234-6630) via Amazon.com. I am reporting the HEPA filter insert (HON24000) as unsafe. It came with a small identifying sticker: RPS Products / BestAir / 847-683-3400. The new HEPA filter insert is white overall. All previous HEPA filter inserts I have purchased for the air purifier have been black outside. I first used the new HEPA filter on 8/13/12. I have operated my air purifier with the new HEPA filter in place three times. All three times when I turned on the unit I immediately noticed a strong organic chemical sort of smell, a smell too objectionable for me to remain in the room. Never before have I experienced any sort of smell when using the air purifier (I have owned it since it was new, perhaps more than 10 years ago, and have purchased and used several replacement HEPA filters and charcoal pre-filters through the years). I ran the air purifier for 3 hours each time on two different days and in two different rooms. The smell was just as strong after each time, so I turned off the air purifier, opened the windows and, after a time, was able to return to the room. On both occasions the next morning I awoke with a sore throat, which was gone by later that morning. A third time I ran the air purifier in my bedroom for 1-1/2 days while I was out of town. The same strong smell was immediately present, and remained as strong after 1-1/2 days of operation. I turned off the air purifier, opened the windows and, after a time, was able to return to the room. I later went to bed in the room. The next morning I again awoke with a sore throat, but this time by midday I was experiencing such low energy that I spent much of the rest of the day lying down. I developed a runny nose and scratchy throat during that day. All my symptoms worsened over the next several days, and I developed a significant c
I am reporting Filterbaby. I have a Filterbaby Skincare Water Filter 2.0 for my bathroom sink. I noticed that over time, colorful gunk has built up in between the clear plastic layers in the front of the device. Water is able to seep in and be trapped. I contacted customer service, whom identified it as mold initially instructed me to clean it, as they did not realize it was inaccessible. Once I reiterated that it's between the clear plastic that cannot be separated, I was told that visible mold build up that can never be cleaned is normal and to continue using the device. I am not going to wash my face with faucet water that continually comes into contact with visible mold. This is a dangerous product that the manufacturer has refused to replace despite their policy on their website that they will replace defective products.

The iSpring WCFM500K system significantly elevates water pH to hazardous levels (9.59) without disclosure, violating EPA/WHO safe drinking water standards (6.58.5 pH). This poses: Health Risks: Skin irritation, potential alkalosis, and disruption of bodily pH balance. Appliance Damage: Accelerated scale buildup in water heaters and plumbing fixtures. 3. Timeline of Events Pre-Purchase Consultation (11/27/2024): I provided iSpring with professional water test results (iron: 1.5 ppm, manganese: 0.665 ppm, pH: 7.88). [REDACTED], iSpring Representative, recommended the WCFM500K system, stating: The WCFM500K will take care of iron and manganese The UVF55FS [UV filter] is always a good option to kill bacteria, which is more common on well water. No warnings about pH elevation were provided. Post-Installation Testing: pH spiked to 9.59, far exceeding safe limits. 3. Evidence of Company Knowledge Chat Transcript (11/27/2024): iSpring reviewed water test results but failed to disclose pH risks.
