When you invest in a HEPA filter you are buying technology that has been tested and approved against a standard. This ensures the quality and reliability of the filter to remove even the tiniest airborne particles. Air filtration is actually more important than many of us realise as indoor air contains many different irritants and pollutants. A correctly chosen HEPA filter can ensure these pollutants are removed efficiently, vastly improving the quality of air you breathe.

Microscopic airborne particles are nearly impossible to see, but can be taken into the lungs and be irritating or damaging to your health, especially for anyone who suffers from allergies or asthma. Larger particles such as pollen, mould spores, dust and other allergens are usually filtered out of our systems in the nose or throat – causing all of those unpleasant symptoms that allergy suffers face. These larger particles are easily removed from the air by a HEPA filter.

State Homeland Security Program (SHSP): The SHSP supports state, tribal, territorial, and local preparedness activities that address high-priority preparedness gaps across all core capabilities that support terrorism preparedness.

HEPAAir Purifier

A HEPA filter is  a specific type of high quality air filter that meets the HEPA filter standard, which is to remove at least 99.97% of particles from the air down to at least 0.3 microns in size. HEPA filters are a common component found in air purifiers which filter the air in order to clean it – there are other types of air purifier such as carbon filter, ionizers and even non-filter purifiers.

The purpose of the FY 2024 HSGP grant is to provide funds to eligible entities to support state, local, tribal, and territorial efforts to prevent terrorism and other catastrophic events and to prepare the Nation for the threats and hazards that pose the greatest risk to the security of the United States. Use the templates below to write a substantial project description.

The OPSG Program funds investments in joint efforts to secure the United States' borders along routes of ingress from international borders to include travel corridors in states bordering Mexico and Canada, as well as states and territories with international water borders.

Smaller particles, such as PM 10 particles, which are only 10 microns in diameter make it past our throat and into our lungs. Even smaller particles, like PM2.5 particles which are 2.5 microns in diameter, can make it right down into the alveoli in our lungs, posing a serious health risk. Most of these tiny particles are pollutants resulting from fossil fuels, traffic or chemicals. It was estimated that small particulate pollution cause around 370,000 premature deaths in Europe in 2005. Scary stuff really! We’ve written a whole other blog post on this subject here.

Weecover max 1 from Weesafe is a special disposable asbestos suit with flat heat-sealed seams for maximum sealing against dangerous fine particles.

It turns out that a particle that is 0.3 microns wide is actually the hardest to filter out of air. So if a HEPA filter removes 99.97% of particles that are 0.3 microns in size, it is even more effective at removing PM10, PM2.5 and the larger allergens such as pollen.

HEPA stands for High Efficiency Particulate Air. A HEPA air filter is made up of thousands of extremely fine fibres arranged into a matt to intercept both microscopic particles and larger ones. An air purifier will push air from the room through the filter to remove pollutant particles. By definition HEPA filters can trap close to 100% of the particles in the air that are 0.3 microns or smaller. (Bearing in mind that there are 10,000 microns in a centimetre, a particle 0.3 microns in diameter is really, really tiny.)

Yes, although HEPA filters are fantastic there are occasions where a non-filter air purifier would be better, for example if you want to kill airborne microbes and bacteria a model which works by incinerating particles, will destroy over  99.99% of micoorganisms. You see, as good a HEPA filters are, they cannot actually destroy anything. So things like mould spores, viruses and bacteria will continue to thrive unhindered unless they are actually destroyed. Something like an Airfree air purifier actually destroys these nasties without the need for replacement filters and are perfect for use in a bedroom or quiet area as they are usually completely silent too. Also, if you have an allergy to mould spores or dust mites, then again, the Airfree type of machine is far and away the best option for you. Destroying the mould spores, in turn kills off the dust mites, which in turn gets rid of the dust mite feces which is one of the most prolific airborne allergens in the home.

The Homeland Security Grant Program supports the core capabilities across the five mission areas of Prevention, Protection, Mitigation, Response, and Recovery based on allowable costs. The HSGP supports the Quadrennial Homeland Security Review Mission to Strengthen National Preparedness and Resilience. HSGP funds a range of activities, including planning, organization, equipment purchase, training, exercises, and management and administration across all core capabilities and mission areas. At least eighty percent (80%) of funds must be passed through to local or tribal units of government. At least thirty-five percent (35%) of the overall HSGP funds received by the state must be dedicated towards law enforcement terrorism prevention activities (LETPA).
