✅ Advantages:

• Affordable: Most DIY tests cost significantly less than hiring a professional
• Accessible: You can order test kits online and do them on your own time
• Empowering: Allows you to take the first step toward solving a potential problem
• Non-invasive: Many tests don’t require drilling, wall removal, or major disruption

⚠️ Disadvantages:

• Easily misused: A good test result may give false reassurance—or a “bad” one may cause unnecessary panic
• Requires interpretation: Many tests require knowledge to read results in context (e.g., what’s “normal” in one region may be elevated in another)
• Limited scope: Most DIY tests focus only on mold, missing other potential contributors like bacteria, VOCs, or dust allergens
• False negatives or positives: Sampling error, test sensitivity, or timing can all skew results

Bottom line: DIY testing is most helpful when paired with good decision-making, realistic expectations, and the willingness to seek help if results are unclear or concerning.
