The flat fold respirator is a flexible medical mask that folds in on itself, making it easy to fit in your pocket, purse, or other small space. The design is also ideal for those who have difficulty achieving a seal with other masks. The flat design allows more of the face to contact the mask, providing a better fit and less irritation. This mask is available in several sizes, so you can find one that fits your head.

What is a flat fold respirator?

N95 masks, which are also referred to as surgical masks, are personal protective equipment (PPE) that protect the wearer from airborne contaminants such as viruses and bacteria, or from liquid contaminating the face. These filtering facepiece respiratory (FFR) masks are regulated by the Centers for Disease Control and Prevention’s National Institute for Occupational Safety and Health (NIOSH) to ensure they offer the advertised level of protection.

In a recent study, researchers compared the fit factors and seal pressures of four molded, cup-shaped N95 FFR models to two flat-fold “one size fits all” FFR models, using human subjects who donned each mask according to manufacturer instructions. Subjects then performed a user seal check with each model, and were allowed to continue performing the test until the mask showed no signs of leakage.

The flat fold masks were found to be more comfortable than the molded masks, with higher seal pressures and fewer reported leakages in both the medium and large-size versions of each. However, the results of this study must be interpreted carefully: the relationship between fit factor and seal pressures is not necessarily linear, and many variables can affect both, including facial anthropometry, skin texture, mask features (e.g., presence of inner flanges, pliable nose bars), and other environmental factors.

Hash for Sale

The cannabis concentrate known as hash is a very potent and pure form of marijuana. It is a solid or semi-solid substance made from the resin glands that collect on the flowers of marijuana plants during the grow process. When smoked or dabbed from a glass pipe or dab rig, hash delivers a very high potency ranging from 40-80% THC. Hash can be found at most dispensaries and will typically cost between $10-$40 per gram.

Hash is much more potent than weed flower as it contains a high concentration of the terpenes (cannabinoids) found in the marijuana plant. Unlike smoking weed, hash does not burn during combustion and therefore produces a clean and smooth smoke. Inhaling hash will produce a very high THC buzz and will usually be felt quickly after inhalation. Mor info https://greensociety.cc/product-category/concentrates/hash/

Unlocking the Power of Hash: How to Buy and Enjoy Premium Cannabis Concentrates

Historically, hash was made by manually rolling the marijuana plant between your hands to strip the sticky trichomes off of the plant and compress it into a solid mass. This is the oldest and most simplistic form of hash creation.

Today, hash can be made using any number of extraction methods ranging from the simple shaking and pressing of cannabis to stainless steel, closed-loop extraction systems that cost tens of thousands of dollars and use butane or carbon dioxide as solvents to extract highly purified cannabis oil with a THC concentration up to 90 percent.

Many home growers will make their own hash by dry sifting their harvested bud, a process that involves running the dried bud through a sieve that creates friction and separates out the resin glands from the rest of the plant material. You can also buy a small hash press, often called a pollen press, that mechanically squeezes kief under pressure into a block of hash.
