3. Pro Mode Filter Cut — Direct Whole Home Filter Test "I want to know everything."

Your Filter Already Has the Data

That dusty filter sitting in your HVAC system has been quietly collecting evidence for months—mold spores, allergens, dust, and particles from every room in your home. FilterCut lets you unlock that data with one simple sample.

What's in the Kit

• Heavy-duty trauma shears (cuts through any filter)
• 4"×4" cutting template
• Nitrile gloves
• Sample collection bag
• Prepaid return mailer
• Step-by-step guide

How It Works

1. Remove your used HVAC filter (must be 30-180 days old)
2. Use the template to cut a 4"×4" sample from the center
3. Bag the sample and drop it in any mailbox
4. Get your results online within 5-7 business days

What You'll Learn

Your detailed lab report identifies 36+ mold species including Stachybotrys (black mold), Aspergillus, Penicillium, Chaetomium, Cladosporium, Alternaria, Fusarium, and 30+ more.

Results are reported in spores per cubic meter—the same standard used by the EPA—so you can compare your home to outdoor baselines and industry guidelines.

Perfect For

• Homeowners who were about to change their filter anyway
• People who want months of accumulated data in one test
• DIYers who don't mind a little hands-on work
• Anyone with a used filter ready to go

Filter Requirements

• Minimum 30 days in service (60-90 days ideal)
• Maximum 180 days old
• Standard pleated or fiberglass filters work best
• Filters with wire mesh? Our shears handle it

Why Cut From the Center?

The center of your filter sees the most consistent airflow and particle capture. Edge samples can be uneven. Center samples give us the cleanest data.
