First order
First order, worst order. Filters were all mismade, damaged and just terrible quality. They did come fast though, but you dont want your UPS driver being Mario Andretti if it means hes gonna crash at every turn. My advice is slow down, take your time and deliver a quality product. I will never use this outfit again.

Hey there! Thanks for your feedback. We're truly sorry to hear about your experience. Receiving filters that arrived damaged and did not meet your expectations is not the experience we want any customer to have. We appreciate you pointing out both the product quality concerns and the condition in which the filters arrived. Your feedback has been shared with our team so we can review both our manufacturing and packaging processes. We understand why this experience would leave you disappointed, and we sincerely apologize that your first order did not reflect the quality we strive to provide. Thank you for giving us a try, and we appreciate you taking the time to share your experience. Filter King.

Super disappointed in shipping time
Super disappointed in shipping time. Their website tells you to buy within a certain amount of time and it’ll get there within a certain day. This is incorrect if it’s the weekend, of course but that should reflect on the website so that it doesn’t influence the customer. In my situation, the website said if I buy within two hours, it would be here next day, today is day 3 and I just received them.

Hey there! Thanks for your feedback. We're very sorry for the frustration and disappointment caused by your delivery experience. We understand how misleading it can be when the estimated delivery timeframe doesn't accurately reflect weekend processing, and we apologize for the confusion. Your feedback is valuable, and we've shared it with our team so we can review how shipping estimates are displayed on our website and make them clearer for future customers. We know how important it is to receive accurate expectations before placing an order. Thank you for bringing this to our attention, and we're sorry that your experience didn't meet your expectations.

Robbed then lied to by FILTER KING
I needed a good quality air filter for my breathing issues. My doctor said MERV 13 or better. Sit filters are expensive and a MERV 13 air filters are very expensive but I paid the extra money to get what my doctors suggested but got ROBBED by FILTER KING!!! I paid extra for MERV 13 but received MERV 8 filters. When I contacted the company they brushed it off and said that they are actually a MERV 13 filter but they encased them in a MERV 8 casing. Does that make any sense! No
Response from Filter KingApr 2, 2026
We’re very sorry for the confusion and frustration this caused. We understand how concerning this is, especially when you specifically ordered MERV 13 filters for your health needs. The frame marking can sometimes cause confusion, but we also recognize that this should have been communicated much more clearly. We’re sorry if our response made you feel dismissed. Please email us at [email protected] with your order details so we can review this properly and make it right. Filter King

Click on advertisement.
I was wondering about the cost, so they give you a code to enter for 10% and they have a 25 dollar for orders over $150, didn't notice that when I placed my order, but once I noticed it wasn't given a discount, I responded to their email of confirmation and I cancel the order, I sent 2 more emails requesting cancelation, 2 days later Matthew response to the cancelation saying the order has shipped, what type of con is this. Wanted to give update, received an email from Daniel, he explained that they dropped the ball and was working to make sure this doesn't happen again, seeing that someone notice and stepped in shows a good stand up company, thanks to Filter King.
