Biotechnology

Controlled environments for cell and gene therapy, vaccine production, and research facilities. We integrate with existing GMP frameworks and help you scale from bench to production.

03 / Semiconductor & Electronics

Semiconductor & Electronics Manufacturing

ISO Class 5 and below cleanrooms for chip fabrication, assembly, and electronics manufacturing where particle counts are mission-critical.

04 / Medical Devices

Medical Devices & Healthcare

Cleanrooms for medical device manufacturing, sterile packaging, and healthcare facilities including compounding pharmacies and research labs.

Why facilities choose us for cleanrooms

Cleanroom HEPA filtration and maintenance systems

We build it AND we maintain it

Most cleanroom contractors finish the project and walk away. We don't. After we build your cleanroom we maintain the HEPA filters, recertify it annually, and stock the replacement parts. One company, one relationship, decades long.

Commercial air filtration expertise at Filter Sales and Service

Filtration is what we actually do

We aren't general contractors who occasionally build cleanrooms. Filter Sales & Service has been a commercial filtration company since 1953. Cleanrooms are the most demanding application of what we do every day, and we've been doing it for over 70 years.

Cleanroom site survey and consultation

We help you decide before we quote

Modular or custom. ISO 5 or ISO 8. Build new or retrofit existing space. We work through these decisions with you in a free site survey before anyone signs anything. You get a recommendation that fits your actual needs, not the project we'd most like to sell.

Filter Sales and Service team, family-owned since 1953

Real humans, every step

You speak to the same people from first call through final certification. No call centers, no account handoffs, no waiting on a ticket. Family-owned since 1953.

What our cleanroom clients say

They didn't just build us a compliant cleanroom, they built us one that actually works for our team's daily workflow. The site survey caught two HVAC issues before we ever signed the contract. That kind of upfront honesty is rare.


Director of Facilities

Pharmaceutical Manufacturing, Cambridge, MA

We've worked with three cleanroom contractors over the past decade. Filter Sales & Service is the only one that's still our partner. They built our ISO 5 suite in 2019 and they're still managing our HEPA program today.


Operations Manager

Biotechnology Company, Boston, MA

I called four contractors for our USP 797 build-out. Two never followed up. One sent a quote without seeing the space. The team at Filter Sales & Service was at our facility within a week and walked us through every option.
