What's included
EverFilter® Air Assessment Kit
The EverFilter® Air Assessment Kit captures what's actually circulating through your home over days of normal system operation.
Each kit includes everything needed to collect, return, and analyze a valid air sample:
- One 4" × 4" EverFilter® sampling media square engineered for airflow-based collection
- Labeled, sealable sample bag to protect the sample after removal
- Prepaid return mailer for simple send-back
- Professional laboratory analysis and digital report
How it works
Professional air sampling made simple
Your HVAC system continuously pulls air from every room in your home. By sampling air at the filter intake, this kit captures what's been circulating through your space during normal operation, not a single-moment snapshot.
- Step 1: CollectPlace the sampling square at your HVAC filter intake by tucking it into the corner of your EverFilter® frame. Let it collect airborne particles during normal system use.
- Step 2: RunRun your system normally for a minimum of 7 days, 14–30 days is recommended.
- Step 3: Send & ReviewRemove the sample, seal it in the labeled bag, and mail it back using the prepaid return mailer. Once analyzed, your results are delivered by email.
This test is an environmental screening tool, not a medical diagnosis. If you have health concerns, share your report with a qualified medical or indoor air quality professional for further evaluation.
What your report shows
You'll receive a clear, easy-to-understand laboratory report showing what contaminants were captured by your filter, measured using professional standards.
- Identification of multiple airborne contaminant categories
- Mold, allergen, particulate, and biological indicators including common indoor and outdoor species
- Results reported in spores per cubic meter
- Comparison to local outdoor baseline levels
- Practical guidance Results are interpreted in context, not as pass/fail scores.
Results are typically emailed within 2–3 business days after lab analysis.
Why this method works
Most air tests capture only a brief moment in time. This assessment uses your HVAC system to sample air continuously, providing a more accurate picture of long-term exposure.
- Uses real air from your home, not a short snapshot
- Lab-verified data instead of assumptions
- Helps guide IAQ improvements and determine whether further investigation is warranted

How it works
Your HVAC System Sees Everything in Your Home
Air doesn't stay in one room. Your system continuously pulls air from every space, carrying whatever comes with it.
Everyday activities introduce particles and gases into your indoor air. Over time, those contaminants circulate through your HVAC system again and again.
The EverFilter® Air Assessment uses your filter intake as a real-world sampling point, capturing what's actually moving through your home, not a single-moment snapshot.
- Captures air from every room, not one location
- Reflects real usage over time, not a quick test
- Uses your HVAC system as a continuous sampler
- Lab-verified insight based on actual airflow
The longer the sampling period, the more representative the results.
Air Assessment vs. In-Home Professional Testing
A smarter first step before spending thousands
Professional in-home air testing and inspections can be highly detailed, but they are also expensive and often unnecessary as a first move. The EverFilter Air Assessment is designed to help you decide if deeper testing is warranted.

1. Your Home's Air Snapshot
We analyzed the particles trapped in your HVAC filter after 30 days in your 3,000–4,000 sq ft home (ZIP 33573). Your results show some moisture indicators and common outdoor mold spores along with pollen and dust.
2. What We Found & What It Means
| Category | Status | What This Means |
|---|---|---|
| Outdoor Molds | Present | 38 spores (Cladosporium, Alternaria) — normal outdoor infiltration. |
| Water-Damage Molds | Present | Moisture indicators detected. Monitor humidity levels. |
| Indoor Molds (Asp/Pen) | Present | 794 spores. Slightly elevated. |
| Growth Indicators | Present | 78 hyphae — monitor humidity. |
| Total Spore Level | Low | Complete registration for detailed calculations. |

Understanding Your Results, QFF Methodology
Purity Air uses Quantitative Filter Forensics (QFF) which analyzes HVAC filters that have been collecting particles for 7–90+ days. Unlike traditional air sampling methods, we do not take an outdoor control sample.
What this means: Traditional methods compare indoor vs. outdoor counts to determine if there's an indoor source. Without an outdoor control, we must assume some level of outdoor infiltration is normal and expected. Any filter that has been in use will capture SOME outdoor spores that infiltrated the building.
Background thresholds applied: Low counts of even "dangerous" molds like Stachybotrys (≤10 spores), Chaetomium (≤15 spores), and Fusarium (≤20 spores) are expected and do NOT indicate an indoor mold problem. Common outdoor molds like Cladosporium (≤500 spores), Ascospores (≤2,000 spores), and Basidiospores (≤1,000 spores) at these levels confirm normal ventilation is working.
Disclaimer: This is a screening tool for informational purposes only and is not a medical test. Results are based on debris found in your filter sample and are not a substitute for professional advice. Spore calculations are estimates based on your registration data. Missing or incomplete registration information may affect accuracy. Because we cannot compare to outdoor levels, our risk thresholds are adjusted higher than traditional indoor air quality assessments. Always consult a certified mold professional for concerns about mold in your home.
