13 best filter medias

Filter media, in the context of aquariums and fishkeeping, refers to the materials used in aquarium filters to remove impurities and maintain water quality. These materials play a crucial role in creating a healthy and balanced aquatic environment for fish and other aquatic life. Here's what you should know about filter media:

  1. Types of Filter Media: There are several types of filter media used in aquarium filtration systems, each serving a specific purpose:

    • Mechanical Filter Media: This type of media physically traps and removes solid particles from the water, such as uneaten fish food, fish waste, and debris. Common mechanical media includes filter sponges, filter floss, and filter pads.
    • Biological Filter Media: Biological media provide a surface for beneficial bacteria to grow. These bacteria help convert toxic ammonia and nitrite into less harmful nitrate through the nitrogen cycle. Common biological media include ceramic rings, bio-balls, and porous stones.
    • Chemical Filter Media: Chemical media can help remove specific impurities from the water, such as dissolved organics, odors, or heavy metals.Examples of chemical media include activated carbon, zeolite, and phosphate removers.
    • Hybrid Media: Some filter media are designed to serve multiple functions, combining mechanical, biological, and chemical filtration in one. These can be convenient for smaller aquariums or specific filtration needs.
  2. Placement in Filters: Filter media are typically placed in different compartments within the filter system. Mechanical media often serve as the first line of defense to remove large particles, followed by biological media to support the growth of beneficial bacteria, and then chemical media if necessary.

  3. Maintenance: Proper maintenance of filter media is essential for efficient aquarium filtration. Mechanical media should be cleaned or replaced regularly to prevent clogs, while biological media should be handled with care to avoid disturbing the beneficial bacterial colonies.

  4. Sizing: Choosing the right size and type of filter media depends on the size of the aquarium, the fish species, and the specific filtration requirements. It's essential to match the media to the filter's capacity and the tank's needs.

  5. Water Quality: Effective filtration using appropriate filter media helps maintain optimal water quality in the aquarium. This, in turn, promotes the health and well-being of the aquatic life.

  6. Chemical Filtration: Chemical filter media like activated carbon can help remove impurities, discoloration, and odor from the water. However, they have a limited lifespan and need to be replaced periodically.

  7. Biological Filtration: Biological media are vital for establishing and maintaining a stable nitrogen cycle in the aquarium. They provide a habitat for beneficial bacteria to colonize and convert harmful ammonia and nitrite into nitrate.

  8. Compatibility: When using chemical media, it's essential to ensure that they are compatible with the needs of your specific aquarium and the fish species you keep. Some chemicals may impact the water parameters or affect certain fish.

In summary, filter media are essential components of aquarium filtration systems, and their selection and maintenance are critical for ensuring a healthy and thriving aquatic environment. Different types of media serve various filtration functions, and their proper use contributes to the overall water quality in the aquarium.

Question: How can i make sure that i'm getting the same filteration as made by kenmore? are these certified hepa filters
Answer: I ordered this item and it does not say anywhere in the item listing on amazon or on the packaging that it is a HEPA filter. On the other hand, Sears sells the HEPA filters for $25.
Question: Is the filter really 6.5 x 4.3 inches as the picture shows? I believe an EF-9 should be more like 4 x
Answer: They are 6.5 X 4.5 (a smidge under, so 4.3 is about right). Just measured mine.

User questions & answers

Question: how often do you change filter
Answer: It's best to change every 4-6 months depending on various factors in and around your home. We recommend checking at the 4 month mark first time around and thereafter monthly to determine the best time to replace it.
Question: Is this eligible for Amazon’s subscription discount
Answer: Nope.
Question: whar does HCF16-16 mean
Answer: HCF 16 is the size, -16 is the merv rating so HCF16-11 would be size 16" and a merv of 11
Question: My unit currently uses a mere 16 filter can I use a lower rated filter
Answer: I would suggest calling the manufacturer of your furnace to ask them for the compatible filters. You should get the correct size that fits your furnace. MERV Ratings: "Higher MERV ratings correspond to a greater percentage of particles captured on each pass, with a MERV 16 filter capturing more than 95% of particles over the full range." Here is a link that discusses MERV furnace filter ratings: https://en.wikipedia.org/wiki/Minimum_efficiency_reporting_value Best of luck!

Answer: 413 Merv rating of 13, 410 Merv rating of 11. MERV stands for Minimum Efficiency Reporting Value, and the MERV rating is the primary rating system used for air filtration. Higher ratings remove a larger percentage and broader range of debris from the air. Note: both filters are 16" x 28" x 4".

User questions & answers

Question: Do you need to wash media when doing a water change? Or do you just leave media in canister and never have to ch media again
Answer: just leave it, if the media gets too plugged up, just rinse it with some( tank )water, otherwise just leave it alone it never needs to be changed.
Question: Do you ever replanish this or one time buy
Answer: This is a one time buy item. You place it in your canister filter and it will become home to beneficial bacteria such as aerobic and anaerobic bacteria that will help breakdown waste products in your water.
Question: I ordered 2 lbs and I received a single package is that actually 2 lbs
Answer: 2ibs is the best size you can get if theres bigger get that depending on how much you'll need. It is worth it in the long run.
Question: How much is needed for a 55 gallon tank
Answer: My thoughts are 1 lb. But I ordered 2 and didn't have room in my filter for all of it. So I would pay more attention to the size of the media baskets on the filter. I use a global 206 and each chamber hours about 1.5 lb so I have one basket full.

Honeywell Air Filter Ultra Efficiency

It's no secret that today's tightly-built homes trap dust, allergens and many more potentially hazardous contaminates. It's also none too surprising that poor indoor air quality ranks among the top five environmental risks to public health.

Honeywell Air Filters are significantly more effective and efficient than standard one-inch fiberglass filters, plus they have the added ability of lasting up to one year! They're also incredibly easy to install and come in accommodating sizes that fit all Honeywell and many of Aprilaire, Space-Gard and Trion Air Bear models.

Be certain to measure the filters you are replacing or your filter boot to make sure it's an exact match. Establish an unrivaled breathing experience for you and your loved ones with Honeywell and their second to none series of Filters.

MERV Rating

MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-12 MERV rating.

About Honeywell

Honeywell's roots reach to 1885, when an inventor named Albert Butz patented the furnace regulator and alarm. He formed the Butz Thermo-Electric Regulator Co., Minneapolis, in April, 1886, and soon invented a device he called the "damper flapper” – an ingenious predecessor to the modern thermostat.

Here's how it worked. When a room cooled below a predetermined temperature, a thermostat closed the circuit and energized an armature. This pulled the stop from the motor gears, allowing a crank attached to the main motor shaft to turn one-half revolution. A chain connected to the crank opened the furnace's air damper to let in air. This made the fire burn hotter. When the temperature rose to the preset level, the thermostat signaled the motor to turn another half revolution, closing the damper and damping the fire. The temperature correction was automatic. Over the years, many Honeywell products have been based upon similar, but more complicated closed-loop systems.

User questions & answers

Question: Will this replace both the carbon and bio max so only this one is necessary
Answer: This is useful if you are having high nitrates to help lower it while also filtering with the mixture of carbon. The bio-max is to help keep good bacteria growing in the aquarium...it’s basically like coral that captures the bacteria and allows it to cling to it helping to meet the natural biological environment needed in your aquarium.
Question: Are these the kind of net bags that you have to fill with the red plastic piece
Answer: No
Question: Whats best way to clean a 10-gal tank? we have 1 large goldfish. daughter won him at a fair. from bowl to 3-gal to 10-gal. algae on glass too
Answer: Goldfish really shouldn't be in a 10 gal. I would get on google/YouTube to learn about proper care.
Question: Does this act like purigen? Does it make the water clearer? Or is that the carbon
Answer: The BioMax media is basically an insert that provides a place for beneficial bacteria to grow. These good bacteria will help reduce the levels of ammonia and nitrite in your system. Purigen is an actual absorbing type product that removes impurities from your system water. I listed some differences between purigen and carbon below.Purigen ) Removes things in the water before they turn into Nitrates slowing water degradation) Clears up the water making it sparkling clear) Can be regenerated multiple times) May last for quite awhile before it is exhausted and needs to be regenerated depending on it use) Does not effect or remove medicines ) Turns darker brown color as it is exhausted and lightens again after regenerationCarbon) Removes most medicines) Cannot be generated) Usually is exhausted relatively quickly) Removes things in the water but does not clear the water) Can leech things back into the water it once removed if it is not changed once exhausted) Shows NO changes as it is exhaustedCarbon is similar to the purigen product in that it absorbs odors, discoloration and impurities in your water but they areHope this helps answer your question.

User questions & answers

Question: Is this washable and reusable? if so, is it easy to clean? i am wanting to use in a diy small pond skimmer/prefilter box
Answer: Although it works fine in filtering, almost to good for my application, I find this product is rather suited to one maybe two use. I have cleaned to reuse but it compresses quite a bit after wet and clogs up quickly with my pond, 3 days. I have 3 large Koi in 350 gallon pond that gets a lot of debris. This filter media reminds me what I used for indoor aquariums. I went back to using large cell foam.
Question: what is the micron size particle removal
Answer: Not sure but I use this at the top layer before the water goes back into my pond and it's fantastic for me. holds a lot and I rinse them and reuse. Love them. I use wow.thepondguy.com for a lot of education as well.
Question: what are the measurements for this pad...length 10 ft.....width?.....thickness
Answer: 10' long, 12" wide, 1.5" thick. Good value - washable and works well in my outdoor pond.
Question: I am looking for a replacement filter for my pool cover pump. Do you think this would work? Whats the difference between the blue and the white? v/r
Answer: The white collects larger particles. This one collect smaller gunk and particles that get thru the white one and works great getting out sludge. I use both. Together they keep my pond nice and clean. I have never tried using the blue alone but I guess some people do and it works great for them.
