Is My Dehumidifier Sufficient Enough?

Is Your Dehumidifier Sufficient Enough?

For homeowners dealing with moisture issues, dehumidifiers are often the first line of defense. But how can you tell if your dehumidifier is sufficient for the job? Depending on the amount of moisture entering your home, particularly through your foundation, you may need a higher PPD (pints per day) dehumidifier or even an additional unit.

Understanding Dehumidifier Capacity

Dehumidifier capacity is measured in PPD, which indicates how many pints of moisture the unit can remove from the air in a day. Choosing the right dehumidifier depends on:

  • The size of the area you want to dehumidify

  • The level of moisture present

  • The source of the moisture (e.g., general humidity vs. water intrusion)

A standard residential dehumidifier might work well for small spaces or moderate humidity, but heavier-duty units are necessary for larger spaces or significant moisture problems.

When Your Dehumidifier Isn’t Enough

If you’re still noticing dampness, musty smells, or mold growth despite running a dehumidifier, it might not be powerful enough. Common signs that you need a higher-capacity or additional unit include:

  • Persistent condensation on windows or walls

  • Slow drying of wet surfaces

  • High humidity readings above 60%

These issues often arise when there’s a continuous influx of moisture, such as water seeping through your foundation. In these cases, a dehumidifier with a higher PPD rating or a second unit might be required to keep up.

How to Choose the Right Dehumidifier

  1. Assess the Moisture Source:

    • If the issue stems from high humidity, a single dehumidifier might suffice for smaller areas.

    • For water intrusion, consider a more robust unit designed for heavy-duty performance.

  2. Consider Room Size:

    • Match the dehumidifier’s capacity to the size of the area. Larger spaces may require multiple units or a commercial-grade dehumidifier.

  3. Factor in Conditions:

    • Basements and crawl spaces with water infiltration often need specialized dehumidifiers with higher PPD ratings.

  4. Check RH Gauge Accuracy:

    • Be cautious of relying entirely on the relative humidity (RH) gauge of inexpensive dehumidifiers. These gauges can often be inaccurate, leading to misleading readings. Always take multiple factors into account when assessing your home’s moisture levels, and consider using a separate, high-quality hygrometer for precise measurements.

The Truth About Mold Remediation: Why Quick Fixes Can Cost You

The Truth About Mold and Why Quick Fixes Can Cost You Mold is a serious issue in any home, and when it comes to selling a property, many homeowners and even contractors try to take shortcuts to cover up the problem. One of the most common misconceptions is that you can simply spray mold, wipe it away, and apply an encapsulant or coat of paint to ‘solve’ the issue—especially before a home inspection. Unfortunately, this method is not only ineffective but can lead to significant legal and financial consequences down the road. The Problem with Covering Up Mold Mold is not just a surface issue—it penetrates materials, releases spores into the air, and can cause health problems for those living in the home. When mold is merely sprayed and wiped away, the underlying issue remains. Moisture is still present, and the mold will likely return, often worse than before. Encapsulating or painting over mold might make it look like it’s gone, but the hidden growth underneath will continue to spread, ...

Do Mold Spray Products Work to Remediate Mold?

Do Mold Spray Products Work to Remediate Mold? When it comes to tackling mold problems, many homeowners turn to mold spray products they find at their local hardware store or online. These products often promise quick and easy solutions—"Spray it on, and boom, the mold is gone!" While these sprays can be a helpful part of the mold remediation process, the reality is far more complex. At Mold Inspection Specialists, we want to help you understand why mold sprays alone may not be the silver bullet for mold issues and how their effectiveness depends on how and when they are used, as outlined by the IICRC S520 standard for professional mold remediation. The Role of Mold Sprays Mold sprays, including those labeled as fungicides or mold removers, are typically designed to kill surface mold and prevent future growth. These products can be effective for cleaning and sanitizing small, isolated patches of mold on non-porous surfaces like tiles, glass, or metal. However, as emphasized b...
