High-efficiency particulate air (HEPA) filters are an essential tool in disaster recovery strategies. The use of disaster recovery ventilation equipment allows response teams to move and purify the air.
This makes it easy to remove unwanted gasses, chemicals, or debris from the air in an area that’s been affected by a disaster. These and other contaminants are removed as the air is passed through HEPA filters.
Knowing how to replace your HEPA filter maximizes the performance of your cleaning equipment while preventing disruptions to your disaster recovery efforts.
HEPA Filter Issues
During a disaster recovery, air contamination poses an additional threat to an area’s occupants. As a result, many disaster recovery strategies must prioritize clean air through the use of HEPA filters.
HEPA filters remove over 99 percent of airborne particles, which protects disaster survivors and recovery personnel. This prevents common health issues such as allergic reactions and illnesses while improving the quality of the air inside recovery spaces.
If your HEPA filter becomes clogged due to excessive use or poor maintenance, its ability to clean the surrounding environment can be impaired. This causes dust, dirt, and other particles to be stirred up rather than removed.
Failing to replace your HEPA filter can also cause damage to your cleaning equipment. Replacing it regularly can protect your equipment and improve its performance over time.
Replacing Your HEPA Filter
Protecting yourself is the first step when replacing your HEPA filter. Operators should cover their noses and mouths with breathing masks before opening filter compartments.
Using rubber gloves can provide additional protection from particles and should be used when replacing your filter. The vacuum should also be disconnected from its power source before opening the filter compartment.
Before replacing the filter, examine it to determine if there are any holes that can let particles through. If the filter is dirty or damaged, you’ll need to replace it immediately.
Prefilters are often used to collect larger pieces of debris. so you may need to remove this first. The prefilter can be rinsed clean, but it should be installed only after it has dried completely.
Filters should be dry, as any moisture can cause electrical issues or promote mould growth. The new HEPA filter should be securely installed prior to replacing the compartment’s cover.
Key Things to Consider
Be sure to assess your vacuum equipment every few months. This allows you to detect any issues early and prevent significant (and costly) problems down the line.
Prefilters may also need to be replaced. Doing so can enhance the lifespan of your HEPA filters. You should also make sure that your new filter is compatible with the equipment in which it is being installed.
Replacing your HEPA filter improves your ability to assist in disaster recoveries. A newly replaced filter removes unwanted debris and air contaminants from the environment so that disaster survivors and recovery teams are kept healthy and safe.
