ONA air fresheners have gained a well-deserved reputation for their long-served time in developing products to combat unwanted odours. Spurring a string of imitation products along the way, ONA air fresheners are still found amongst the arsenal of products in almost every hydroponic grower’s tool box. If you have a plant that even the most hardy of grow room carbon filters cannot deal with, or even if you feel the area could do with a nice fresh scent ONA Block Air Fresheners make the perfect choice.

HOW ONA AIR FRESHENER BLOCKS WORK

The ONA Air Freshener Blocks are a combination of 32 different essential oils set in a wax-like block. Simply place the container where you are having problems with bad grow room odours, open the lid and the block begins to do its job! Any odours in the vicinity are completely eradicated, leaving you with a fresh smelling house. As the blocks evaporate they will shrivel up and lose their effectiveness, so make sure you replace each ONA Block air freshener as and when needed.

ONA Block Air fresheners come in a variety of two scents, ‘Fresh Linen’ and ‘Pro’ ‘Fresh linen’ masks and eliminates grow room smells and leaves in place the sweet scent of freshly washed clothes. The ‘Pro’ version is the most effective at removing and replacing bad or unwanted plant smells, but the smell is slightly more industrial than the ‘Fresh Linen’ version. Either one you choose, the scent is discreet and effective.

The ONA Block Air Fresheners are ideal for combating bad odours in smaller environment (like a single bedroom) or ideal to be placed throughout your extraction system, as a fail-safe to your carbon filter.  For larger areas, you may need to make use of the ONA Gel.

WHERE TO PLACE ONA AIR FRESHENERS

For best practice, place the ONA blocks in the environment surrounding the grow room where odours have become a problem. Alternatively, you can place the ONA block itself within the ducting of your extraction system, after the fan and filter. ONA have developed a custom-made fitting to add to your ducting to make this an even easier task. All extracted air is then forced over the ONA block, creating an ideal fail-safe in the event your carbon filter can no longer cope.

Ideally, you do not want to place these air fresheners directly in your hydroponics grow room, next to your growing plants. The terpenes or molecules the ONA Block releases can react with your plant and potentially taint its usual fragrance or flavour. This is particularly crucial when/if you are drying your harvest. In drying rooms, which usually have lower amount of air movement, the direct exposure to the compounds released by ONA Blocks will have a potentially higher effect.

HOW ONA AIR FRESHENERS GET RID OF BAD SMELLS

ONA Block Air Fresheners works via the secret blend of 32 essential oils. This broad spectrum of oils works in a variety of ways on unwanted odours, not just masking any prevailing odour, but also neutralising them too. As ONA Blocks use only natural, food grade ingredients they are 100% non toxic, so health and safety to people is of minimal concern.

The essential oils work by three distinct different modes of action. This ensures that unwanted plant smells are both masked and, to a degree, removed. The three modes of action are as follows:

  1. Absorption – The smells (or volatile organic compound’s (VOC’s)) are completely retained within the compounds released by ONA Blocks.
  2. Adsorption – Similarly to how activated carbon works in filter’s the unwanted VOC’s are essentially stuck onto the surface of the compounds released from ONA Blocks
  3. Chemical Reaction – Permanent bondage of the odour molecule and the active ONA Block ingredients. Particularly through the ‘Zwaardermaker Pairs Theory’, where two or more VOC’s can form a natural bond/attraction and cancel each other out.

A typical hydroponic grow room will contain plants that are creating and releasing all sorts of VOC’s, a class of which being terpenes. Terpenes and other VOC’s evaporate faster at higher temperatures, so you are likely to notice hot days being more problematic than cool ones. Terpenes and other VOC’s have a wide range of physical characteristics, so the 32 oils having these three modes of action to remove smells gives you peace of mind for a great price.

TIPS ON USING ONA BLOCKS

You can increase the length of time they last for by piercing holes in the lid rather than opening up the entire thing. The reduced air flow over the waxy block will slow down the rate at which it expires.

On the flipside, if you have an excessively smelly room that needs some intense treatment, you can take the waxy block out of the container altogether. This exposes its entire surface are to the air, meaning you get the maximum air freshening effect possible, although this does significantly reduce its longevity.

Keep a few spare ONA blocks handy, when they do run out, it’s always best to be able to replace them straight away rather than risk smells making their way out.

Fantastic to use towards the end of your extraction system (after the carbon filter). Not only does this ensure your extracted air is squeaky clean, but also smelling as fresh as a daisy.
