Many customers say replacement filters arrive in the right size and work as expected. Several reviews highlight fast shipping, easy ordering, and lower prices than name-brand options. Others report wrong sizes, damaged or contaminated filters, and coupon codes that do not work. Ratings reflect a clear split between very positive and very negative experiences.
Examples from available reviews (Apr 2018 – Mar 2026).
Received correct filters on time, in good condition, at a low price.
“The filters were received on time, in good condition, and precisely as ordered - and at a low price.”
Found hard-to-find parts that fit a 20-year-old Kenmore perfectly.
“Filters fit perfectly for my 20 year old Kenmore vacuum , hard to find parts for older items but this place did excellent!”
Tier 1 filter performed poorly, causing sand and damage; support was unhelpful.
“the filter proceeded to fill my entire home with sand”
Price doubled at checkout and company refused to honor advertised price.
“the price on the confirmation screen was double the price that was listed on the product page.”
Fast shipping, in-stock items, and helpful phone staff come up often. Several reviewers describe getting expedited replacements after shipping mistakes. Another recurring set of comments mentions long delivery times, wrong items, missing return labels, and disputes over refunds.
Many customers point to lower prices than name-brand filters and say performance is comparable. Some mention unclear pricing or promotional offers being denied, but these comments appear less often than the positive price feedback. One review specifically describes a checkout incident where the price doubled.
Multiple reviewers say the website is easy to use, with clear part lookup and ordering steps. Some ran into checkout problems or orders that did not process and only fixed them by calling. A few reviewers attributed late deliveries to postal delays rather than the seller.
Many reviews describe sturdy filters that fit well, improve water taste, and reduce noise. A contrasting group reports defects such as dye leaks, sand release, chemical smells, or poor construction on arrival. Complaints range from small fit issues to reports of serious contamination or damage.
Several reviews mention account tracking that makes reordering easier. Many complaints focus on coupon codes that do not work, generic delay updates, and orders that sit unprocessed without clear ship dates. Positive examples of communication appear, but far less often than the complaints.
Feedback divides between repeat buyers who cite reliable fit, good prices, and simple reorders, and customers who received wrong parts, damaged items, or service problems that were not resolved. Reviews include both fast, effective fixes and unresolved situations that led to strongly negative ratings.
For each review, the core experience based on original source reviews.

I'm not sure what kind of marketing tricks they are pulling, but this company has been amazing! After my Samsung filter was damaged in shipment through no fault of their own and I had to take time off work. Discount Filters got me a replacement order on the way right away so that we could get back up running again as soon possible..I cannot say enough good things about these guys. They are truly one-upping themselves by being an industry leader and providing outstanding service for all customers alike. I wish more vendors would treat customers like them :) I would and have recommended this company to others.
