Made in the USA, it installs quickly using included stainless steel wire clips and maintains 70% airflow, ensuring optimal ventilation for furnaces, boilers, and water heaters while preventing costly damage from pests. ## Description The American made PVS-IS3 three inch PVC vent screen offers maximum protection for high efficiency furnace, boiler and hot water heater ventilation systems. While most plastic solutions only guard against animals, the PVS-IS3 maintains a comparable airflow while also providing guarding against bees, wasps and other bugs that may find their way into your home. The PVS-IS3 is designed for new installations and also to replace inefficient plastic PVC caps or guards. The PVS-IS3 maintains a 70% rate of airflow by utilizing a high quality 18x18 316 stainless steel mesh screen that is enclosed in a durable 6061-T6 aluminum shell. Included with each PVC vent screen purchase are two 304 stainless steel internal wire clips to securely hold the vent screen in place inside a 3” PVC pipe hub. All materials are anti-corrosive and will not become brittle as plastic caps, guards and covers so often do. Review: High quality product with matching price tag - Had a difficult time pulling the trigger on this item as it is expensive given the simple nature of the product. Looked around and couldn't find a viable alternative and considered making my own for roughly 1/3 the cost but decided in this case that my time was more valuable than the price savings given the number of projects I'm currently working on. Used this screen in the 2" inch pvc pipe that is an inlet for the blower for an advance treatment unit of my septic system. Given the blower is $800 dollars on its own I wanted this screen as the first step in keeping stuff out of the tight tolerance of the blowers impeller, along with 2 additional layers of air filtering. The product is high quality and fit perfectly into the 3x2 reducer on the 2" air intake pipe, didn't want to restrict air flow so used the reducer instead of ordering a 2" screen. Happy with the purchase but if there was a less expensive alternative I would likely have purchased the less expensive item. Review: Super high quality! - These are super high quality. The easy installation provides a very secure fit. I used the fine mesh for the intake and the larger mesh for the exhaust on my high efficiency gas heater. The large mesh is required on the outlet to prevent water vapor in the exhaust gas from freezing and obstructing the exhaust. ## Features - Made in the United States - Insect And Rodent Protection - 316 Stainless Steel Screen - Internal Wire Clips Included - Installs in Seconds ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 50 Reviews | ## Images ![3" Insect and Rodent Model PVS-IS3 Replaces Inefficient Cap and Guard Covers - Image 1](https://m.media-amazon.com/images/I/71PJFQh4ZqL.jpg) ![3" Insect and Rodent Model PVS-IS3 Replaces Inefficient Cap and Guard Covers - Image 2](https://m.media-amazon.com/images/I/71tJI5oP6rL.jpg) ![3" Insect and Rodent Model PVS-IS3 Replaces Inefficient Cap and Guard Covers - Image 3](https://m.media-amazon.com/images/I/71U7AW6WJCL.jpg) ## Questions & Answers **Q: My pipe has a 2 3/8 " internal diam. What size do I need? 2" seems too small, 3" seems too big.** A: Neither you need 2 3/8" one and I don't know if you can get one. Research for a 2 3/8" one if no results you may have to make your own screen. Screen can be purchased at any hardware supply, **Q: will this stop noseeums?** A: Don’t know what they -are they anything ‘yeseeeums’? **Q: Will this stop mosquitos?** A: I do believe the mesh screen holes are small enough to prevent mosquitos as the holes are smaller than that of window screens (if I remember correctly). I must add that I purchased this to prevent wasps from entering the HVAC furnace exhaust and was very happy with the build quality, speed of shipment and delivery. **Q: Will this work with 3 inch ABS** A: Yes, it will work with either 3-inch ABS or 3-inch PVC. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality product with matching price tag *by M***P on April 18, 2017* Had a difficult time pulling the trigger on this item as it is expensive given the simple nature of the product.

Small pests shouldn't be able to get past it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/33018181-3-insect-and-rodent-model-pvs-is3-replaces-inefficient-cap](https://www.desertcart.co.th/products/33018181-3-insect-and-rodent-model-pvs-is3-replaces-inefficient-cap) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-07*
