Summary
It all depends where you live -- what the air pollution levels are in your area, and what kinds of pollutants you have inside your house.

One should at least inspect the filter every 30 days and change it if necessary. If clean, check at least every 45 days. If a central air conditioning and heating system is used regularly, the filter should be changed at least once a year.

A filter change costs a couple of dollars, but it is the most important thing you can do to avoid problems later. if you let it go, the blower motor works harder, shortening its life or your evaporator coil could become your filter, blocking airflow and causing it to start icing up; this can cost hundreds of dollars to remedy.

If you smoke in your house, have inside pets, or a large amount of traffic in the house, check the filter once a week. The outside environment should be considered, since dust storms and high pollution areas do affect the filter as well.

How often do you change the sand in the filter?

A sand filter will generally require a sand bed change once every 7 to 10 years. It may be less depending on various factors. Should the pressure gauge on the filter read 10lbs higher than original start-up pressure (when the filter was first installed), backwash the filter. Should the pressure gauge still read 8-10lbs higher (after backwashing) than the original start-up pressure, this is a good indication that the sand bed requires replacement.

How do you change an AC filter?

the filter is easy to change. it should be in one or two places, the return grill which will be in a hallway near the thermostat. this is the most common location if your furnace is located someplace not easily gotten to. the return grill should have a small latch(es) or screws/nuts keeping it closed, the grill is hinged to allow it to swing open for easy filter changes. simply remove old filter check the size that's written on it and replace with same size assuming it fit right. lil trick if it's high up turn on the fan this will hold the filter when you have your hands full balancing on a ladder/chair. replace it every 2 to 3 months depending how it looks. If your furnace is in the garage or a closet and you only have a flat return grill the filter will be in the bottom of the furnace, just open the bottom door and you will see it, pull it out and replace. the filter needs to have some kind of support in it, checkerboarded thread at least to keep it from being sucked into the blower motor when it starts collecting dust. they only cost a couple of bucks at walmart or a do it yourself store. pleated ones have more surface area and work great. hope i helped. viking40

How often should you change the sand in a sand pool filter?

i too would like to know, some here say 5-6 years old but pool professional told me 1-2 years im confused. :/ As the Installation and Service Manager at abovegroundpros.com, your sand in your sand filter is expected to last around 4 yrs. There are factors that can lessen the time frame and others that can lengthen the time frame. I recommend all to change out every 3-4 yrs as a rule of thumb. This will help make sure that your filter sand does not get overly filled with debris, causing your filtration system to not work at its peak performance. Remember to always backwash your filter after you have changed your sand, before placing it on filtration. In cases like this its better to be safe then to be sorry.

How often should you change the oil and filter in your 2009 Dodge Challenger SE?

The 3,000 mile oil change interval has been pounded into the head of consumers for decades. It had a scientific basis when engines used non detergent oil. It no longer has any scientific basis in fact. The oil change industry and some dealers are still promoting this even though it is not necessary. This is called the "Cheap Insurance Myth". The 3,000 mile oil change is a total waste of money and oil in 2010. Most manufactures recommend 5,000 to 7,500 mile oil change intervals and some even recommend 10,000 miles. With modern lubricants and oil filters it is not necessary to change your oil as you did decades ago. If you use conventional oil and drive normally then change your oil/filter every 5,000 miles. If you use synthetic change it every 7,500 miles. Your engine will be protected and you will save money and oil. There is one make and model car that I would recommend you change the oil every 3,000 miles. The Saturn S Series requires you use the 3,000 mile interval due to a manufacturing flaw. The timing chain tensioner on these vehicles uses oil pressure to control tension and is very sensitive to varnish buildup that can clog the oil port. So on a Saturn S Series change the oil/filter every 3,000 miles.

How often should you change a 3 gallon in-tank filter?

Filter media should never need changing. You can rinse of debris in the old tank water at each weekly water change, but throwing away sponges can actually ruin your water quality! You throw away the majority of the good bacteria that keeps your water quality healthy. I have healthy sponges over 7 years old in one of my tanks. You should only ever replace filter sponges if you're restarting the tank, or they've got tatty and need replacing. And you can only replace them in two stages, letting the new sponges run alongside the old for several weeks before throwing away the old. If you had a larger filter that had two or sponges in there, you can replace one at a time, but if it's only in a 3 gallon (which is a TINY tank) I doubt you have this!

How often should the fuel filter be changed on a Chevy suburban?

I personally change my fuel filter on all my vehicles every other oil change. But my fuel filters are about 5 to 10 bucks. Unless yours is outrageously expensive you should consult your owners manual. It will never hurt to change as often as you want but not to replace it often enough will result in poor gas mileage an maybe damage to the fuel pump itself. Plus you will have a lack of performance an a sluggish feeling when accelerating. Your owner's manual list the scheduled maintenance on the fuel filter. Fuel today is pretty clean so changing it every other oil change is overkill but will not hurt. It is just a waste of money. I would recommend every 50,000 miles unless the owners manual states more often.
